JAK1 Antibody – Mouse Monoclonal

JAK1: a widely expressed non-receptor tyrosine-kinase involved in the interferon-alpha/beta and -gamma signal transduction pathways. Couples cytokine ligand binding to tyrosine phosphorylation of various known signaling proteins and of a unique family of transcription factors termed the signal transducers and activators of transcription, or STATs. A selective Jak1 inhibitor induces apoptosis in NRP-154 prostate cancer cell line. A single mutation seen in tyrosine kinome screen of colon cancers. Activated in B cell lines from patients with post-transplant lymphoproliferative disorder, and in a mouse Lck-driven T cell lymphoma. Inhibitor: Piceatannol.
