Chain A   (SC24B_HUMAN | O95487)
molecular function
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0005215    transporter activity    Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells.
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
    GO:0048208    COPII vesicle coating    The addition of COPII proteins and adaptor proteins to ER membranes during the formation of transport vesicles, forming a vesicle coat.
    GO:0006888    ER to Golgi vesicle-mediated transport    The directed movement of substances from the endoplasmic reticulum (ER) to the Golgi, mediated by COP II vesicles. Small COP II coated vesicles form from the ER and then fuse directly with the cis-Golgi. Larger structures are transported along microtubules to the cis-Golgi.
    GO:0019886    antigen processing and presentation of exogenous peptide antigen via MHC class II    The process in which an antigen-presenting cell expresses a peptide antigen of exogenous origin on its cell surface in association with an MHC class II protein complex. The peptide antigen is typically, but not always, processed from a whole protein.
    GO:0002474    antigen processing and presentation of peptide antigen via MHC class I    The process in which an antigen-presenting cell expresses a peptide antigen on its cell surface in association with an MHC class I protein complex. Class I here refers to classical class I molecules.
    GO:0035909    aorta morphogenesis    The process in which the anatomical structures of an aorta are generated and organized. An aorta is an artery that carries blood from the heart to other parts of the body.
    GO:0002093    auditory receptor cell morphogenesis    Any process that alters the size or shape of an auditory receptor cell.
    GO:0060088    auditory receptor cell stereocilium organization    A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a stereocilium. A stereocilium is an actin-based protrusion from the apical surface of auditory hair cells.
    GO:0072358    cardiovascular system development    The process whose specific outcome is the progression of the cardiovascular system over time, from its formation to the mature structure. The cardiovascular system is the anatomical system that has as its parts the heart and blood vessels.
    GO:0021747    cochlear nucleus development    The process whose specific outcome is the progression of the cochlear nucleus over time, from its formation to the mature structure.
    GO:0060982    coronary artery morphogenesis    The process in which the anatomical structures of coronary arteries are generated and organized. Coronary arteries are blood vessels that transport blood to the heart muscle.
    GO:0006886    intracellular protein transport    The directed movement of proteins in a cell, including the movement of proteins between specific compartments or structures within a cell, such as organelles of a eukaryotic cell.
    GO:0060463    lung lobe morphogenesis    The process in which the anatomical structures of a lung lobe are generated and organized. A lung lobe is a projection that extends from the lung.
    GO:0060425    lung morphogenesis    The process in which the anatomical structures of the lung are generated and organized.
    GO:0001843    neural tube closure    The last step in the formation of the neural tube, where the paired neural folds are brought together and fuse at the dorsal midline.
    GO:0003151    outflow tract morphogenesis    The process in which the anatomical structures of the outflow tract are generated and organized. The outflow tract is the portion of the heart through which blood flows into the arteries.
    GO:0015031    protein transport    The directed movement of proteins into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0061156    pulmonary artery morphogenesis    The process in which the anatomical structures of the pulmonary artery are generated and organized. The pulmonary artery is the artery that carries blood from the heart to the lungs.
    GO:1901301    regulation of cargo loading into COPII-coated vesicle    Any process that modulates the frequency, rate or extent of cargo loading into COPII-coated vesicle.
    GO:0090178    regulation of establishment of planar polarity involved in neural tube closure    Any process that modulates the rate, frequency, or extent of the establishment of planar polarity involved in neural tube closure, the coordinated organization of groups of cells in the plane of an epithelium that contributes to the closure of the neural tube.
    GO:0006810    transport    The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
    GO:0016192    vesicle-mediated transport    A cellular transport process in which transported substances are moved in membrane-bounded vesicles; transported substances are enclosed in the vesicle lumen or located in the vesicle membrane. The process begins with a step that directs a substance to the forming vesicle, and includes vesicle budding and coating. Vesicles are then targeted to, and fuse with, an acceptor membrane.
cellular component
    GO:0030127    COPII vesicle coat    One of two multimeric complexes that forms a membrane vesicle coat. COPII is best characterized in S. cerevisiae, where the subunits are called Sar1p, Sec13p, Sec31p, Sec23p, and Sec24p. Vesicles with COPII coats are found associated with endoplasmic reticulum (ER) membranes at steady state.
    GO:0030134    COPII-coated ER to Golgi transport vesicle    A vesicle with a coat formed of the COPII coat complex proteins. The COPII coat complex is formed by the Sec23p/Sec24p and the Sec13p/Sec31p heterodimers. COPII-associated vesicles transport proteins from the rough endoplasmic reticulum to the Golgi apparatus (anterograde transport).
    GO:0012507    ER to Golgi transport vesicle membrane    The lipid bilayer surrounding a vesicle transporting substances from the endoplasmic reticulum to the Golgi.
    GO:0005794    Golgi apparatus    A compound membranous cytoplasmic organelle of eukaryotic cells, consisting of flattened, ribosome-free vesicles arranged in a more or less regular stack. The Golgi apparatus differs from the endoplasmic reticulum in often having slightly thicker membranes, appearing in sections as a characteristic shallow semicircle so that the convex side (cis or entry face) abuts the endoplasmic reticulum, secretory vesicles emerging from the concave side (trans or exit face). In vertebrate cells there is usually one such organelle, while in invertebrates and plants, where they are known usually as dictyosomes, there may be several scattered in the cytoplasm. The Golgi apparatus processes proteins produced on the ribosomes of the rough endoplasmic reticulum; such processing includes modification of the core oligosaccharides of glycoproteins, and the sorting and packaging of proteins for transport to a variety of cellular locations. Three different regions of the Golgi are now recognized both in terms of structure and function: cis, in the vicinity of the cis face, trans, in the vicinity of the trans face, and medial, lying between the cis and trans regions.
    GO:0000139    Golgi membrane    The lipid bilayer surrounding any of the compartments of the Golgi apparatus.
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0005783    endoplasmic reticulum    The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).
    GO:0005789    endoplasmic reticulum membrane    The lipid bilayer surrounding the endoplasmic reticulum.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0048471    perinuclear region of cytoplasm    Cytoplasm situated near, or occurring around, the nucleus.
