|Official Full Name||eukaryotic translation initiation factor 1A, X chromosome|
|Background||Eukaryotic translation initiation factor 1A, X-chromosomal is a protein that in humans is encoded by the EIF1AX gene. Mammalian 17-kDa eukaryotic initiation factor, eIF1A (formerly designated eIF-4C), is essential for transfer of the initiator Met-tRNAf (as Met-tRNAf·eIF2·GTP ternary complex) to 40 S ribosomal subunits in the absence of mRNA to form the 40 S preinitiation complex (40 S·Met-tRNAf·eIF2·GTP). Furthermore, eIF1A acts catalytically in this reaction to mediate highly efficient transfer of the Met-tRNAf·eIF2·GTP ternary complex to 40 S ribosomal subunits. The 40 S complex formed is free of eIF1A which indicates that its role in 40 S preinitiation complex formation is not to stabilize the binding of Met-tRNAf to 40 S ribosomes. Additionally, the eIF1A-mediated 40 S initiation complex formed in the presence of AUG codon efficiently joins 60 S ribosomal subunits in an eIF5-dependent reaction to form a functional 80 S initiation complex. Though found in some reports, eIF1A probably plays no role either in the subunit joining reaction or in the generation of ribosomal subunits from 80 S ribosomes. The major function of eIF1A is to mediate the transfer of Met-tRNAf to 40 S ribosomal subunits to form the 40 S preinitiation complex.|

EIF1AX has several biochemical functions, for example, poly(A) RNA binding, protein binding, translation factor activity, RNA binding. Some of the functions are cooperated with other proteins, some of the functions could acted by EIF1AX itself. We selected most functions EIF1AX had, and list some proteins which have the same functions with EIF1AX. You can find most of the proteins on our site.
