molecular function
    GO:0005524    ATP binding    Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
    GO:0016887    ATPase activity    Catalysis of the reaction: ATP + H2O = ADP + phosphate + 2 H+. May or may not be coupled to another reaction.
    GO:0042623    ATPase activity, coupled    Catalysis of the reaction: ATP + H2O = ADP + phosphate; this reaction directly drives some other reaction, for example ion transport across a membrane.
    GO:0055131    C3HC4-type RING finger domain binding    Interacting selectively and non-covalently with a C3HC4-type zinc finger domain of a protein. The C3HC4-type zinc finger is a variant of RING finger, is a cysteine-rich domain of 40 to 60 residues that coordinates two zinc ions, and has the consensus sequence: C-X2-C-X(9-39)-C-X(1-3)-H-X(2-3)-C-X2-C-X(4-48)-C-X2-C, where X is any amino acid. Many proteins containing a C3HC4-type RING finger play a key role in the ubiquitination pathway.
    GO:0001664    G-protein coupled receptor binding    Interacting selectively and non-covalently with a G-protein coupled receptor.
    GO:0023026    MHC class II protein complex binding    Interacting selectively and non-covalently with the class II major histocompatibility complex.
    GO:0019899    enzyme binding    Interacting selectively and non-covalently with any enzyme.
    GO:0031072    heat shock protein binding    Interacting selectively and non-covalently with a heat shock protein, any protein synthesized or activated in response to heat shock.
    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
    GO:0001786    phosphatidylserine binding    Interacting selectively and non-covalently with phosphatidylserine, a class of glycophospholipids in which a phosphatidyl group is esterified to the hydroxyl group of L-serine.
    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:0031625    ubiquitin protein ligase binding    Interacting selectively and non-covalently with a ubiquitin protein ligase enzyme, any of the E3 proteins.
    GO:0051082    unfolded protein binding    Interacting selectively and non-covalently with an unfolded protein.
biological process
    GO:0046034    ATP metabolic process    The chemical reactions and pathways involving ATP, adenosine triphosphate, a universally important coenzyme and enzyme regulator.
    GO:0008380    RNA splicing    The process of removing sections of the primary RNA transcript to remove sequences not present in the mature form of the RNA and joining the remaining sections to form the mature form of the RNA.
    GO:0009267    cellular response to starvation    Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of deprivation of nourishment.
    GO:0051085    chaperone mediated protein folding requiring cofactor    The process of assisting in the correct posttranslational noncovalent assembly of proteins, which is dependent on additional protein cofactors. This process occurs over one or several cycles of nucleotide hydrolysis-dependent binding and release.
    GO:0061684    chaperone-mediated autophagy    The autophagy process which begins when chaperones and co-chaperones recognize a KFERQ-related motif and unfold the substrate protein. The proteins are then transported to the lysosome where they are degraded.
    GO:1904764    chaperone-mediated autophagy translocation complex disassembly    The disaggregation of a chaperone-mediated autophagy translocation complex into its constituent components.
    GO:0061741    chaperone-mediated protein transport involved in chaperone-mediated autophagy    The chaperone-mediated protein transport process in which a protein that is bound to a chaperone and a lysosomal receptor is unfolded and transported into the lysosome as part of chaperone-mediated autophagy.
    GO:0072318    clathrin coat disassembly    The disaggregation of a clathrin coat into its constituent components; results in stripping or removing the clathrin coat from clathrin-coated vesicles (CCV) before fusing with their targets. CVVs transport cargo from plasma membrane and trans-Golgi to the endosomal system.
    GO:0061738    late endosomal microautophagy    The autophagy process by which cytosolic proteins targeted for degradation are tagged with a chaperone and are directly transferred into and degraded in a late endosomal compartment.
    GO:0006397    mRNA processing    Any process involved in the conversion of a primary mRNA transcript into one or more mature mRNA(s) prior to translation into polypeptide.
    GO:0000398    mRNA splicing, via spliceosome    The joining together of exons from one or more primary transcripts of messenger RNA (mRNA) and the excision of intron sequences, via a spliceosomal mechanism, so that mRNA consisting only of the joined exons is produced.
    GO:1902904    negative regulation of supramolecular fiber organization    Any process that stops, prevents or reduces the frequency, rate or extent of fibril organization.
    GO:0045892    negative regulation of transcription, DNA-templated    Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0007269    neurotransmitter secretion    The regulated release of neurotransmitter from the presynapse into the synaptic cleft via calcium regualated exocytosis during synaptic transmission.
    GO:0048026    positive regulation of mRNA splicing, via spliceosome    Any process that activates or increases the rate or extent of mRNA splicing via a spliceosomal mechanism.

    GO:0005730    nucleolus    A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus.

During cis-splicing, the initial target RNA is a single, contiguous RNA transcript, whether mRNA, snoRNA, etc., and the released products are a spliced RNA and an excised intron, generally as a lariat structure. During trans-splicing, there are two initial substrate RNAs, the spliced leader RNA and a pre-mRNA.

biological process
    GO:0006915    apoptotic process    A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died.
    GO:0007166    cell surface receptor signaling pathway    A series of molecular signals initiated by activation of a receptor on the surface of a cell. The pathway begins with binding of an extracellular ligand to a cell surface receptor, or for receptors that signal in the absence of a ligand, by ligand-withdrawal or the activity of a constitutively active receptor. The pathway ends with regulation of a downstream cellular process, e.g. transcription.
    GO:0070389    chaperone cofactor-dependent protein refolding    The process of assisting in the restoration of the biological activity of an unfolded or misfolded protein, which is dependent on additional protein cofactors.
