Background

Function：Component of the 43S pre-initiation complex (43S PIC), which binds to the mRNA cap-proximal region, scans mRNA 5'-untranslated region, and locates the initiation codon (PubMed:11166181, PubMed:22813744, PubMed:24319994). In this complex, acts as a GTPase-activating protein, by promoting GTP hydrolysis by eIF2G (EIF2S3) (PubMed:11166181). During scanning, interacts with both EIF1 (via its C-terminal domain (CTD)) and EIF1A (via its NTD) (PubMed:22813744). This interaction with EIF1A contributes to the maintenance of EIF1 within the open 43S PIC (PubMed:24319994). When start codon is recognized, EIF5, via its NTD, induces eIF2G (EIF2S3) to hydrolyze the GTP (PubMed:11166181). Start codon recognition also induces a conformational change of the PIC to a closed state (PubMed:22813744). This change increases the affinity of EIF5-CTD for EIF2-beta (EIF2S2), which allows the release, by an indirect mechanism, of EIF1 from the PIC (PubMed:22813744). Finally, EIF5 stabilizes the PIC in its closed conformation (PubMed:22813744)

Subcellular Localization：Cytoplasm

Subunit：Component of the 43S pre-initiation complex (43S PIC), which is composed of the 40S ribosomal subunit, EIF1, eIF1A (EIF1AX), eIF3 complex, EIF5 and eIF2-GTP-initiator tRNA complex (eIF2 ternary complex). Interacts with eIF1A (EIF1AX) during scanning (PubMed:24319994). Interacts through its C-terminal domain (CTD) with EIF1 or with eIF2-beta (EIF2S2) (mutually exclusive) through a common binding site (PubMed:21745818, PubMed:22813744). Interacts through its C-terminal domain (CTD) with the CTD of EIF5B (PubMed:30211544). Interacts with FMR1 isoform 6; this interaction occurs in a RNA-dependent manner (PubMed:24658146)
