General description

Eukaryotic translation termination factor 1 (eRF1) is a protein encoded by the ETF1 gene in humans. It belongs to eRF1 family and the amino-acid sequence is highly conserved.

Application

Anti-eRF1 antibody produced in rabbit has been used in western blotting and immunoprecipitation.

Biochem/physiol Actions

Eukaryotic translation termination factor 1 (eRF1) proteins are directly implicated in the termination of translation in eukaryotes. It plays an important role in the termination of protein synthesis, which is performed by three domains (N, M and C) of eRF1. Rearrangement in eRF1 leads to N-domain accommodation into the ribosomal A site.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
