Anti-EIF3A / Eukaryotic translation initiation factor 3 subunit A

0.5mg/ml if reconstituted with 0.2ml sterile DI water. Eukaryotic translation initiation factor 3 subunit A (eIF3a) is a protein that in humans is encoded by the EIF3A gene. Enables RNA binding activity. Contributes to translation initiation factor activity. Involved in IRES-dependent viral translational initiation, formation of cytoplasmic translation initiation complex, and viral translational termination-reinitiation. Located in cytosol, nucleolus, and nucleoplasm. Part of eukaryotic translation initiation factor 3 complex. Protein function: RNA-binding component of the eukaryotic translation initiation factor 3 (eIF-3) complex, which is required for several steps in the initiation of protein synthesis (PubMed:17581632, PubMed:25849773). The eIF-3 complex associates with the 40S ribosome and facilitates the recruitment of eIF-1, eIF-1A, eIF-2:GTP:methionyl- tRNAi and eIF-5 to form the 43S pre-initiation complex (43S PIC). The eIF-3 complex stimulates mRNA recruitment to the 43S PIC and scanning of the mRNA for AUG recognition. The eIF-3 complex is also required for disassembly and recycling of post-termination ribosomal complexes and subsequently prevents premature joining of the 40S and 60S ribosomal subunits prior to initiation (PubMed:17581632, PubMed:11169732). The eIF-3 complex specifically targets and initiates translation of a subset of mRNAs involved in cell proliferation, including cell cycling, differentiation and apoptosis, and uses different modes of RNA stem- loop binding to exert either translational activation or repression (PubMed:25849773, PubMed:27462815).
