LTK (gene)
Introduction
Leukocyte tyrosine kinase, also known as LTK, is a human gene.[1]
The protein encoded by this gene is a member of the ros/insulin receptor family of tyrosine kinases. Tyrosine-specific phosphorylation of proteins is a key to the control of diverse pathways leading to cell growth and differentiation. Two alternatively spliced transcript variants encoding different isoforms have been described for this gene.[1]
