Synj2 Gene Summary [Mouse]
Enables phosphatidylinositol-4,5-bisphosphate 5-phosphatase activity. Predicted to be involved in inositol phosphate catabolic process; phosphatidylinositol dephosphorylation; and synaptic vesicle endocytosis. Predicted to be located in axon terminus; cytoplasmic microtubule; and ruffle membrane. Predicted to be active in membrane; perinuclear region of cytoplasm; and presynapse. Is expressed in several structures, including alimentary system; genitourinary system; nose; spleen; and submandibular gland primordium. Orthologous to human SYNJ2 (synaptojanin 2).

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 Synj2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
