Recombinant Human LCK, His-tagged

Cat. No.: LCK -692H
Product Overview: Recombinant, human Lck fused to a His Tag sequence and expressed inS. frugiperda insect cells.Lck is a member of the Src tyrosine kinases that plays a role in T cell activation and in the regulation of mitochondrial apoptosis pathways.
Description: LCK (p56lck) is a member of the src family of non-receptor tyrosine kinases. It was identified as a gene rearranged and overexpressed in the murine lymphoma LSTRA, most likely as a result of the insertion of Moloney murine leukemia virus DNA immediately adjacent to the gene. Lck behaves as a proto-oncogene and can lead to cell transformation upon activation. A number of human cancer cell lines show overexpression of LCK, pointing to a possible role for this kinase in the initiation and maintenance of the transformed state in human cancers.
Source: S. frugiperda insect cells.
