Lck sh4
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 … WebLck is the major Src family protein tyrosine kinase essential for early T cell signaling (Shaw et al., 1990; Turner et al., 1990 ). It consists of consecutive SH4, SH3, SH2, and tyrosine kinase (SH1) domains, with the N-terminal membrane-proximal SH4 domain being myristoylated and double-palmitoylated.

WebThe 18-amino acid Src homology 4 (SH4) domain membrane anchor of Lck is necessary and sufficient for Nef-mediated retargeting, but other details of this process are not known. The goal of this study was therefore to identify characteristics of SH4 domains responsive to Nef and the transport machinery used.

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.
