Syk Gene Summary [Mouse]
Enables several functions, including ATP binding activity; SH2 domain binding activity; and enzyme binding activity. Involved in several processes, including cell surface receptor signaling pathway; myeloid cell activation involved in immune response; and regulation of vesicle-mediated transport. Acts upstream of or within several processes, including positive regulation of lymphocyte activation; positive regulation of macromolecule metabolic process; and protein phosphorylation. Located in early phagosome. Part of B cell receptor complex. Is expressed in liver and notochord. Human ortholog(s) of this gene implicated in immunodeficiency 82. Orthologous to human SYK (spleen associated tyrosine kinase). [provided by Alliance of Genome Resources, Jul 2025]

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