Recombinant Human LCK Protein , N-GST-tagged
Product Description
Cat
IMP-9779
Official Symbol
LCK
Product Overview
Recombinant human Active Lck protein with a N-GST tag was expressed in Spodoptera frugiperda, Sf 9 cells.
Description
This gene is a member of the Src family of protein tyrosine kinases (PTKs). The encoded protein is a key signaling molecule in the selection and maturation of developing T-cells. It contains N-terminal sites for myristylation and palmitylation, a PTK domain, and SH2 and SH3 domains which are involved in mediating protein-protein interactions with phosphotyrosine-containing and proline-rich motifs, respectively. The protein localizes to the plasma membrane and pericentrosomal vesicles, and binds to cell surface receptors, including CD4 and CD8, and other signaling molecules. Multiple alternatively spliced variants encoding different isoforms have been described.
