Eukaryotic translation initiation factor 1A, X-chromosomal (eIF1A) is a protein that in humans is encoded by the EIF1AX gene. [5] [6] [7] This gene encodes an essential eukaryotic translation initiation factor. The protein is a component of the 43S pre-initiation complex (PIC), which mediates the recruitment of the small 40S ribosomal subunit to the 5' cap of messenger RNAs. [7]
eIF1A is a small protein (17 kDa in budding yeast) and a component of the 43S preinitiation complexes (PIC). eIF1A binds near the ribosomal A-site, in a manner similar to the functionally related bacterial counterpart IF1. [8]
Mutations in this gene have been recurrently seen associated to cases of uveal melanoma with disomy 3. [9] eIF1A is mutated in thyroid cancers. [10]
RNA-binding protein 8A is a protein that in humans is encoded by the RBM8A gene.
Eukaryotic translation initiation factor 4 gamma 2 is a protein that in humans is encoded by the EIF4G2 gene.
Eukaryotic translation initiation factor 4 gamma 1 is a protein that in humans is encoded by the EIF4G1 gene.
Eukaryotic translation initiation factor 2 subunit 1 (eIF2α) is a protein that in humans is encoded by the EIF2S1 gene.
Eukaryotic translation initiation factor 3 subunit A (eIF3a) is a protein that in humans is encoded by the EIF3A gene. It is one of the subunits of Eukaryotic initiation factor 3 (eIF3) a multiprotein complex playing major roles in translation initiation in eukaryotes.
MAP kinase-interacting serine/threonine-protein kinase 1 is an enzyme that in humans is encoded by the MKNK1 gene.
Eukaryotic translation initiation factor 4 gamma 3 is a protein that in humans is encoded by the EIF4G3 gene. The gene encodes a protein that functions in translation by aiding the assembly of the ribosome onto the messenger RNA template. Confusingly, this protein is usually referred to as eIF4GII, as although EIF4G3 is the third gene that is similar to eukaryotic translation initiation factor 4 gamma, the second isoform EIF4G2 is not an active translation initiation factor.
Eukaryotic initiation factor 4A-I is a 46 kDa cytosolic protein that, in humans, is encoded by the EIF4A1 gene, which is located on chromosome 17. It is the most prevalent member of the eIF4A family of ATP-dependant RNA helicases, and plays a critical role in the initiation of cap-dependent eukaryotic protein translation as a component of the eIF4F translation initiation complex. eIF4A1 unwinds the secondary structure of RNA within the 5'-UTR of mRNA, a critical step necessary for the recruitment of the 43S preinitiation complex, and thus the translation of protein in eukaryotes. It was first characterized in 1982 by Grifo, et al., who purified it from rabbit reticulocyte lysate.
Eukaryotic translation initiation factor 4B is a protein that in humans is encoded by the EIF4B gene.
Eukaryotic translation initiation factor 3 subunit B (eIF3b) is a protein that in humans is encoded by the EIF3B gene.
Eukaryotic translation initiation factor 3 subunit H (eIF3h) is a protein that in humans is encoded by the EIF3H gene.
Eukaryotic translation initiation factor 5 is a protein that in humans is encoded by the EIF5 gene.
Eukaryotic translation initiation factor 3 subunit F (eIF3f) is a protein that in humans is encoded by the EIF3F gene.
Eukaryotic translation initiation factor 3 subunit D (eIF3d) is a protein that in humans is encoded by the EIF3D gene.
Eukaryotic translation initiation factor 4E transporter is a protein that in humans is encoded by the EIF4ENIF1 gene.
Eukaryotic translation initiation factor 5B is a protein that in humans is encoded by the EIF5B gene.
Eukaryotic translation initiation factor 1 (eIF1) is a protein that in humans is encoded by the EIF1 gene. It is related to yeast SUI1.
Eukaryotic translation initiation factor 1A, Y-chromosomal is a protein that in humans is encoded by the EIF1AY gene.
Importin-13 is a protein encoded by the IPO13 gene in humans. Importin-13 is a member of the importin-β family of nuclear transport receptors (NTRs) and was first identified as a transport receptor in 2000. According to PSI-blast based secondary structure PREDiction (PSIPRED), importin-13 contains 38 α-helices. Importin-13 accommodates a range of cargoes due to its flexible superhelical structure and a cargo binding and release system that is distinct from other importin-like transport receptors. IPO13 is broadly expressed in a variety of tissues in the human body, including the heart, cornea, fetal lung, brain, endometrial carcinoma, and testes.
Eukaryotic Initiation Factor 2 (eIF2) is an eukaryotic initiation factor. It is required for most forms of eukaryotic translation initiation. eIF2 mediates the binding of tRNAiMet to the ribosome in a GTP-dependent manner. eIF2 is a heterotrimer consisting of an alpha, a beta, and a gamma subunit.
