SMG7 Rabbit Polyclonal Antibody

SMG7, nonsense mediated mRNA decay factor (SMG7) Homo sapiens This gene encodes a protein that is essential for nonsense-mediated mRNA decay (NMD) ; a process whereby transcripts with premature termination codons are targeted for rapid degradation by a mRNA decay complex. The mRNA decay complex consists, in part, of this protein along with proteins SMG5 and UPF1. The N-terminal domain of this protein is thought to mediate its association with SMG5 or UPF1 while the C-terminal domain interacts with the mRNA decay complex. This protein may therefore couple changes in UPF1 phosphorylation state to the degradation of NMD-candidate transcripts. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Aug 2011], function:Plays a role in nonsense-mediated mRNA decay. Recruits RENT1 to cytoplasmic mRNA decay bodies., similarity:Contains 2 TPR repeats., subcellular location:Predominantly cytoplasmic, and nuclear. Shuttles between nucleus and cytoplasm., subunit:Part of a complex that contains SMG5, SMG7, PP2AC, a short isoform of UPF3A (isoform UPF3AS, but not isoform UPF3AL) and phosphorylated RENT1.
