Pik3c3 Gene Summary [Mouse]

Enables protein kinase activity. Involved in cellular response to glucose starvation; macroautophagy; and synaptic vesicle endocytosis. Acts upstream of or within several processes, including phosphatidylinositol-3-phosphate biosynthetic process; protein localization to phagophore assembly site; and protein phosphorylation. Located in phagocytic vesicle. Part of phosphatidylinositol 3-kinase complex, class III. Is active in GABA-ergic synapse; endosome; and glutamatergic synapse. Is expressed in several structures, including Meckel's cartilage; cardiovascular system; limb; and skeleton. Orthologous to human PIK3C3 (phosphatidylinositol 3-kinase catalytic subunit type 3).

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Pik3c3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
