T cell receptor signaling co-regulates multiple Golgi genes to enhance N-glycan branching.

Abstract

T cell receptor (TCR) signaling enhances beta1,6GlcNAc-branching in N-glycans, a phenotype that promotes growth arrest and inhibits autoimmunity by increasing surface retention of cytotoxic T lymphocyte antigen-4 (CTLA-4) via interactions with galectins. N-Acetylglucosaminyltransferase V (MGAT5) mediates beta1,6GlcNAc-branching by transferring N… (More)
