Eukaryotic translation initiation factor 5A-2

UniProtKB accession:  Q93VP3

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Translation factor that promotes translation elongation and termination, particularly upon ribosome stalling at specific amino acid sequence contexts (By similarity). Binds between the exit (E) and peptidyl (P) site of the ribosome and promotes rescue of stalled ribosome: specifically required for efficient translation of polyproline-containing peptides as well as other motifs that stall the ribosome (By similarity). Acts as a ribosome quality control (RQC) cofactor by joining the RQC complex to facilitate peptidyl transfer during CAT tailing step (By similarity). Regulates cytokinin-mediated root protoxylem specification and represses secifically the expression of AHP6 (PubMed:24163315). Regulates the induction of programmed cell death caused by infection with virulent pathogen (PubMed:17513484, PubMed:18633122).
