Chain A (CD1D1_MOUSE | P11609)

molecular function
	GO:0042608	T cell receptor binding	Interacting selectively and non-covalently with a T cell receptor, the antigen-recognizing receptor on the surface of T cells.
	GO:0030881	beta-2-microglobulin binding	Interacting selectively and non-covalently with beta-2-microglobulin.
	GO:0050839	cell adhesion molecule binding	Interacting selectively and non-covalently with a cell adhesion molecule.
	GO:0030883	endogenous lipid antigen binding	Interacting selectively and non-covalently with an endogenous cellular lipid antigen.
	GO:0030884	exogenous lipid antigen binding	Interacting selectively and non-covalently with an exogenous lipid antigen (examples include microbial lipids and glycolipids).
	GO:0042393	histone binding	Interacting selectively and non-covalently with a histone, any of a group of water-soluble proteins found in association with the DNA of eukaroytic chromosomes. They are involved in the condensation and coiling of chromosomes during cell division and have also been implicated in nonspecific suppression of gene activity.
	GO:0030882	lipid antigen binding	Interacting selectively and non-covalently with a lipid antigen.
	GO:0071723	lipopeptide binding	Interacting selectively and non-covalently with a lipopeptide, any of a group of organic compounds comprising two or more amino acids linked by peptide bonds and containing a nonprotein group consisting of a lipid or lipids.
	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).
biological process
	GO:0001865	NK T cell differentiation	The process in which a precursor cell type acquires the specialized features of a NK T cell.
	GO:0019882	antigen processing and presentation	The process in which an antigen-presenting cell expresses antigen (peptide or lipid) on its cell surface in association with an MHC protein complex.
	GO:0048006	antigen processing and presentation, endogenous lipid antigen via MHC class Ib	The process in which an antigen-presenting cell expresses lipid antigen of endogenous origin in association with an MHC class Ib protein complex on its cell surface. Class Ib here refers to non-classical class I molecules, such as those of the CD1 family.
	GO:0048007	antigen processing and presentation, exogenous lipid antigen via MHC class Ib	The process in which an antigen-presenting cell expresses lipid antigen of exogenous origin in association with an MHC class Ib protein complex on its cell surface. Class Ib here refers to non-classical class I molecules, such as those of the CD1 family.
	GO:0006955	immune response	Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat.
	GO:0002376	immune system process	Any process involved in the development or functioning of the immune system, an organismal system for calibrated responses to potential internal or invasive threats.
	GO:0045087	innate immune response	Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.
	GO:0051135	positive regulation of NK T cell activation	Any process that activates or increases the frequency, rate or extent of natural killer T cell activation.
	GO:0051138	positive regulation of NK T cell differentiation	Any process that activates or increases the frequency, rate or extent of natural killer T cell differentiation.
	GO:0001916	positive regulation of T cell mediated cytotoxicity	Any process that activates or increases the frequency, rate or extent of T cell mediated cytotoxicity.

cellular component
	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.
