Eukaryotic release factor 3 a (eRF3a) is encoded by the gene G1 to S phase transition 1 (GSPT1) in humans. The eRF3a/GSPT1 exon 1 is a translation termination protein characterized with a tri-nucleotide GGC repeat coding for a polyglycine expansion in the amino-terminal end.
免疫原
synthetic peptide corresponding to amino acids 190-204 of human eRF3a/GSPT1, conjugated to KLH via a C-terminal added cysteine residue. The sequence is conserved in human, rat, and mouse.
アプリケーション
Anti-eRF3a/GSPT1 antibody produced in rabbit has been used in immunoprecipitation, indirect immunofluorescence and western blotting.
生物化学的／生理学的作用
Eukaryotic release factor 3 a (eRF3a) is proteolytically processed into an IAP (Inhibitors of Apoptosis Proteins)-binding protein. Processed eRF3a interacts with IAPs and can promote caspase activation, IAP ubiquitination and apoptosis. The IAP binding motif is exposed only after proteolytic cleavage of a 69-residue leader sequence. eRF3a also affects mRNA stability and translation initiation by interacting with Poly(A)-binding protein (PABP) and the surveillance factor Upf1.
Eukaryotic release factor 3a (eRF3a) is a translation termination protein that is encoded by G1 to S phase transition 1 gene (GSPT1) in humans. The eRF3a/GSPT1 exon 1 contains a tri-nucleotide GGC repeat coding for a polyglycine expansion in the N-terminal of the protein. It is associated with protein translation as a regulator of apoptosis signal-regulating kinase 1 (ASK1). GSPT1 interacts with ASK1 and enhances ASK1-induced apoptotic activity by activating caspase-3. It plays a novel role in the regulation of ASK1-mediated apoptosis. GSPT1 is found to be up-regulated in various human cancers and is considered as a potential proto-oncogene.

The human eukaryotic release factor 3a (eRF3a), encoded by the G1 to S phase transition 1 gene (GSPT1; alias eRF3a), is upregulated in various human cancers. GSPT1 contains a GGC(n) polymorphism in exon 1, encoding a polyglycine expansion in the
Apoptosis signal-regulating kinase 1 (ASK1), a member of the mitogen-activated protein kinase kinase kinase family, plays a critical role in mediating apoptosis signals initiated by a variety of death stimuli such as hydrogen peroxide and tumor necrosis factor-alpha. Owing to
