Lyn Gene Summary [Mouse]
Enables SH3 domain binding activity; non-membrane spanning protein tyrosine kinase activity; and phosphatidylinositol 3-kinase activator activity. Involved in several processes, including cell surface receptor signaling pathway; protein phosphorylation; and regulation of signal transduction. Acts upstream of or within several processes, including B cell receptor signaling pathway; neuroinflammatory response; and regulation of release of sequestered calcium ion into cytosol. Located in several cellular components, including membrane raft; nucleus; and plasma membrane. Part of protein-containing complex. Is expressed in several structures, including alimentary system; genitourinary system; hemolymphoid system gland; liver and biliary system; and nervous system. Used to study systemic lupus erythematosus. Orthologous to human LYN (LYN proto-oncogene, Src family 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 Lyn often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
