Automated description from the Alliance of Genome Resources (Release 3.2)
Exhibits SH3 domain binding activity and non-membrane spanning protein tyrosine kinase activity. Involved in several processes, including immune response-regulating cell surface receptor signaling pathway; immune system development; and regulation of signal transduction. Localizes to several cellular components, including membrane raft; nucleus; and plasma membrane. 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).
