Target Details for LCK

Target: LCK (Lymphocyte-Specific Protein tyrosine Kinase (LCK))

Alternative Name: Lck

Background: The p56[lck] protein kinase is a member of the src family of cytoplasmic protein-tyrosine kinases (PTKs). Members of this family have several common features: 1) unique N-terminal domains, 2) attachment to cellular membranes through a myristylated N-terminus, and 3) homologous SH2, SH3, and catalytic domains. Within the src family of PTKs, lck, fyn, and Yes are expressed in T cells. The unique N-terminal domain of p56[lck] interacts with the cytoplasmic tails of the CD4 and CD8 cell surface glycoproteins. CD4 and CD8 bind to surface major histocompatibility complex (MHC) class II and class I molecules, respectively. These complexes interact with the T cell antigen receptor (TCR) in the early stages of T cell activation. In addition, an activated lck kinase increases responsiveness of some T cell hybridomas to antigen. The phosphorylation status and, therefore, the activity of p56[lck] kinase is regulated by the CD45 tyrosine protein phosphatase. Several studies suggest that lck has many functions critical to T cell development and activation. Mice lacking a functional lck gene are drastically impaired in the production of T lymphocytes. Variants of the human Jurkat T cell line that do not express p56[lck] exhibit a diminished response to stimulation of the T cell receptor. Evidence suggests that lck is directly upstream from PI3-kinase in the signal transduction cascade in T cell activation.
