Anti-eRF3a/GSPT1 (N-terminal) 兔抗

synthetic peptide corresponding to amino acids 99-116 of human eRF3a/GSPT1, conjugated to KLH via a C-terminal added cysteine residue.

Anti-eRF3a/GSPT1 (N-terminal) antibody produced in rabbit is suitable for immunoprecipitation at a concentration of 2-5μL using HeLa cell lysates and western blotting at a dilution of 1:500-1:1,000 using HeLa cell lysates.

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.
