Function | ATP-binding RNA helicase involved in translation initiation. Part of the 43S pre-initiation complex that is required for efficient initiation on mRNAs of higher eukaryotes with structured 5'-UTRs by promoting efficient NTPase-dependent 48S complex formation. Specifically binds to the 40S ribosome near the mRNA entrance. Does not possess a processive helicase activity. |
Subunit | Part of the 43S pre-initiation complex (PIC) that contains at least Met-tRNA, EIF1, EIF1A (EIF1AX or EIF1AY), EIF2S1, EIF2S2, EIF2S3, EIF3A, EIF3B, EIF3C, EIF3D, EIF3E, EIF3F, EIF3G, EIF3H, EIF3I, EIF3J, EIF3K, EIF3L, EIF3M, DHX29 and the 40S ribosomal subunit. |
Subunit | Part of the 43S pre-initiation complex (PIC). |
Catalytic activity | RHEA:13065: ATP + H2O = ADP + H(+) + phosphate
EC 3.6.4.13 |
Subcellular location | Cytoplasm. |
