Syt3 Gene Summary [Mouse]
Enables calcium-dependent phospholipid binding activity; protein heterodimerization activity; and protein homodimerization activity. Involved in regulation of postsynaptic membrane neurotransmitter receptor levels. Is active in postsynapse. Is expressed in several structures, including eye; genitourinary system; heart; nervous system; and respiratory system. Orthologous to human SYT3 (synaptotagmin 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 Syt3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
