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. Web19 mei 2000 · The Lck SH4 domain indeed predominantly targeted the chimeric protein into GEMs. In transfectants derived from wild-type Jurkat cells, but not in those derived from the Lck-deficient mutant, the LckSH4-CD3ζ protein was constitutively tyrosine-phosphorylated.
