Lck, active
N-terminal 6His-tagged recombinant, human full length Lck.
Biological information
Background
The lck protooncogene is a member of the src-related gene family of non-receptor tyrosine kinases. It is uniquely expressed only in T-lymphocytes and NK-cells. The p56lck kinase (LCK) is a 56 KD polypeptide that is associated with a cytoplasmic face of the plasma membrane. It functions as a critical signalling model in IL-2 signal transduction leading to T-lymphocyte activation. Specifically, it has been shown that a stable complex exists between IL-2 receptors and p56lck and that treatment of T-lymphocytes with IL-2 promotes p56lck kinase activity and rapid phosphorylation of cellular substrates. In addition, p56lck has been found to function as a signal transducer for antigen activated CD4 and CG8 T-cell receptors and plays a role in thymic maturation of certain T-cells. The CD45 antigen, a receptor/protein tyrosine phosphatase of T-cells, also interacts with p56lck.
