eukaryotic translation initiation factor 1A, Y-chromosomal isoform 1 [Homo sapiens]

Protein Classification

eukaryotic translation initiation factor 1A( domain architecture ID 10794364)

eukaryotic translation initiation factor 1A (eIF1A) may be required for maximal rate of protein biosynthesis; it enhances ribosome dissociation into subunits and stabilizes the binding of the initiator Met-tRNA(I) to 40 S ribosomal subunits

 33-109 2.49e-44

S1_IF1A: Translation initiation factor IF1A, also referred to as eIF1A in eukaryotes and aIF1A in archaea, S1-like RNA-binding domain. S1-like RNA-binding domains are found in a wide variety of RNA-associated proteins. IF1A is essential for translation initiation. eIF1A acts synergistically with eIF1 to mediate assembly of ribosomal initiation complexes at the initiation codon and maintain the accuracy of this process by recognizing and destabilizing aberrant preinitiation complexes from the mRNA. Without eIF1A and eIF1, 43S ribosomal preinitiation complexes can bind to the cap-proximal region, but are unable to reach the initiation codon. eIF1a also enhances the formation of 5'-terminal complexes in the presence of other translation initiation factors. This protein family is only found in eukaryotes and archaea.
