Description_x000D_ Biochem/physiol Actions_x000D_ LYN (proto-oncogene) belongs to the src family of tyrosine kinases. It controls cancer cell growth, migration, invasion and survival. Upregulation of LYN is associated with shorter overall survival in breast cancer. LYN shows anti- or pro-apoptotic effects. It can enhance AKT (v-akt murine thymoma viral oncogene homolog) phosphorylation or suppress AKT activation. It is also responisble for activation of p58 PI3K (phosphatidylinositol-4,5-bisphosphate 3-kinase). Activation of LYN-PI3K-AKT signaling enhances myeloma proliferation._x000D_ Physical form_x000D_ Supplied in 50 mM Tris-HCl, pH 7.5, with 150 mM NaCl, 0.25 mM DTT, 0.1 mM EGTA, 0.1 mM EDTA, 0.1 mM PMSF, and 25% glycerol._x000D_ Legal Information_x000D_ PRECISIO is a registered trademark of Sigma-Aldrich Co.
