Webco-immunoprecipitate with the Lck SH4 domain is therefore dispensable for the retargeting effect. This also suggests that retargeting of LckN18.GFP to the TGN upon ectopic expres- sion of Unc119a likely reflects a dominant-negative effect on SH4 domain transport because of sequestration of Unc119a ligands essential for transport. Web15 sep. 2000 · Lck contains a unique domain at the NH 2 terminus (Src homology 4 (SH4) domain), followed by an SH3 domain, an SH2 domain, and a tyrosine kinase or SH1 domain ().It has been shown that each of the kinase, SH3, and SH2 domains plays a crucial role in TCR-mediated signal transduction (6, 7).The kinase domain is required for ITAM …
