eIF3G is an RNA-associated protein involved in protein synthesis. It is a member of the eIF-3 subunit G family and the largest of the eukaryotic translation initiation factor family with eukaryotic translation initiation factor-3 (eIF3) being a multiprotein complex composed of at least 13 different subunits. eIF3G...

Phosphorylation of the eukaryotic initiation factor 2 (eIF2) alpha subunit is a well-documented mechanism to downregulate protein synthesis under a variety of stress conditions. eIF2 binds GTP and Met-tRNAi and transfers Met-tRNA to the 40S subunit to form the 43S preinitiation complex (1,2). eIF2 promotes a new...

eIF3J is an RNA-associated protein belonging to the eukaryotic translation initiation factor family. It belongs to the group of proteins involved in protein translation:synthesis where it binds to the 40S ribosomal subunit and promotes the binding of methionyl-tRNAi and mRNA to form the 40S initiation complex. eIF3J...

It is a member of the eIF-3 subunit G family and the largest of the eukaryotic translation initiation factor family with eukaryotic translation initiation factor-3 (eIF3) being a multiprotein complex composed of at least 13 different subunits. eIF3G...

Translation initiation requires a set of factors to facilitate the association of the 40S ribosomal subunit with mRNA. The eIF4F complex, consisting of eIF4E, eIF4A and eIF4G, binds to the 5' cap structure of mRNA (1). eIF4F and eIF4B unwind the secondary structure of mRNA at its 5' untranslated region (1). The 40S...

eIF3A is an important protein involved in protein translation:synthesis. It is a 1382aa member of the eIF-3 subunit A family with a PCI domain and a component of the eIF-3 multiprotein complex composed of at least 13 different subunits. It interacts with eIF3B and intermediate filament protein K7 (cytokeratin 7). A...

A variety of factors contribute to the important biological event of initiation of translation. The eIF4F complex of translation initiation factors binds to the 5' m7 GTP cap to open up the mRNA secondary structure and allow small ribosome subunit binding (1). eIF4A, an eIF4 complex component that acts as an...

eIF-4B (eukaryotic translation initiation factor 4B),an RNA binding protein, is essential for the binding of mRNA to the 43S pre-initiation complex, which consists of the 40S ribosomal subunit bound to a ternary complex of eIF-2, GTP, and Met-tRNA stabilized by eIF-3. An arginine rich motif (ARM) in the...

Eukaryotic initiation factor 4B (eIF4B) is thought to assist the eIF4F complex in translation initiation. In plants, eIF4B is known to interact with the poly-(A) binding protein, increasing its poly-(A) binding activity (1). Heat shock and serum starvation cause dephosphorylation of eIF4B at multiple sites with...

A variety of factors contribute to the important biological event of initiation of translation. The eIF4F complex of translation initiation factors binds to the 5' m7 GTP cap to open up the mRNA secondary structure and allow small ribosome subunit binding (1). eIF4A, an eIF4 complex component that acts as an...

eIF4A1 is a 406aa ATP-dependent RNA helicase belonging to the DEAD box helicase family and eukaryotic initiation factor-4A subfamily with a helicase ATP-binding domain and a helicase C-terminal domain. eIF4F eukaryotic translation initiation complex is formed by the association of eIF4A1 with eIF4E and eIF4E kinase...

eIF4A2 is a 407aa ATP-dependent RNA helicase, belonging to the DEAD box helicase family. It contains one helicase ATP-binding domain and a helicase C-terminal domain. eIF4A2, a subunit of the eIF4F complex, acts as a protein-synthesis initiation factor and thus plays an important role in the binding of mRNA to the...
