A Quality Control Pathway That Down-regulates Aberrant T-cell Receptor (TCR) Transcripts by a Mechanism Requiring UPF2 and Translation

Abstract excerpt

Nonsense-mediated decay (NMD) is an RNA surveillance pathway that degrades mRNAs containing premature termination codons (PTC). T-cell receptor (TCR) and immunoglobulin (Ig) transcripts, which are encoded by genes that very frequently acquire PTCs during lymphoid ontogeny, are down-regulated much more dramatically in response to PTCs than are other known transcripts. Another feature unique to TCR, Ig, and a...
