Description
Catalytic Activity
ATP + H(2)O = ADP + phosphate.
Function
ATP-binding RNA helicase involved in translation initiation. Part of the 43S preinitiation complex that is required for efficient initiation on mammalian mRNAs 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. {ECO:0000269|PubMed:19109895, ECO:0000269|PubMed:23706745}.
Similarity
Belongs to the DEAD box helicase family. DEAH subfamily. {ECO:0000305}.
Similarity
Contains 1 helicase ATP-binding domain. {ECO:0000255|PROSITE-ProRule:PRU00541}.
Similarity
Contains 1 helicase C-terminal domain. {ECO:0000255|PROSITE-ProRule:PRU00542}.
Subcellular Location
Cytoplasm {ECO:0000305}.
Subunit
Part of the 43S preinitiation complex 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. {ECO:0000269|PubMed:23706745}.
