Previous GeneCards Identifiers for GSPT2 Gene
This gene encodes a GTPase that belongs to the GTP-binding elongation factor family. The encoded protein is a polypeptide release factor that complexes with eukaryotic peptide chain release factor 1 to mediate translation termination. This protein may also be involved in mRNA stability.[provided by RefSeq, Mar 2010]
GeneCards Summary for GSPT2 Gene
GSPT2 (G1 To S Phase Transition 2) is a Protein Coding gene. Among its related pathways are Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein and Gene Expression. GO annotations related to this gene include GTP binding and GTPase activity. An important paralog of this gene is GSPT1.
UniProtKB/Swiss-Prot for GSPT2 Gene
Involved in translation termination in response to the termination codons UAA, UAG and UGA. May play a role as a potent stimulator of the release factor activity of ETF1. Exhibits GTPase activity, which is ribosome- and ETF1-dependent. May play a role in cell cycle progression. Component of the transient SURF complex which recruits UPF1 to stalled ribosomes in the context of nonsense-mediated decay (NMD) of mRNAs containing premature stop codons.
