LTK, Leukocyte tyrosine kinase, Protein tyrosine kinase 1, TYK1
Product description
Leukocyte tyrosine kinase (LTK) is a receptor-type protein tyrosine kinase, belonging to the insulin receptor superfamily, and is mainly expressed in B lymphocyte precursors and neuronal tissues. LTK utilizes insulin receptor substrate-1 (IRS-1) and Shc as major two substrates and possesses two NPXY motifs for them separately, tyrosine 485 of one NPXY motif at the juxtamembrane domain for IRS-1 and tyrosine 862 of another NPXY motif at the carboxyl-terminal domain for Shc. It has also been shown that p85 subunit of PI3 kinase directly binds to tyrosine 753 of LTK, which is located within a YXXM motif. Tyrosine 485 and 753 are responsible for IRS-1 and PI3K mediated survival effects of LTK, respectively.
