LcKGST SH3 domain protein.N-terminal GST tagged Lck SH3 domain.Human lymphocyte specific kinase (Lck) is involved in Tcelland IL2-receptor signaling. Lck SH3 domain is the SH3 domain of Lck tyrosine kinase. SH3 domains are known tobind proline rich peptides. The Lck SH3 domain has beenexpressed as a fusion protein with GST allowing expression in E. coli and purification by affinity chromatography.The native GST-Lck-SH3 is the ideal tool for in vitro/in vivoinvestigations of the behaviour of cellular prions. It maybe used for protein-protein interaction studies as well asfor in vitro/in vivo conversion studies.The GST-Tag facilitates the protein's application in typicalGST pull-down assays.
