GeneCards Summary for EIF3B Gene:

EIF3B (eukaryotic translation initiation factor 3, subunit B) is a protein-coding gene. Diseases associated with EIF3B include mouth disease, and tetralogy of fallot, and among its related super-pathways are Eukaryotic Translation Initiation and Formation of the ternary complex, and subsequently, the 43S complex. GO annotations related to this gene include protein complex scaffold and nucleotide binding.

UniProtKB/Swiss-Prot: EIF3B_HUMAN, P55884

Function: Component of the eukaryotic translation initiation factor 3 (eIF-3) complex, which is required for

several steps in the initiation of protein synthesis. 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 preinitiation

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

About This Section

UniProtKB/Swiss-Prot: EIF3B_HUMAN, P55884 (See protein sequence)

Recommended Name: Eukaryotic translation initiation factor 3 subunit B

Size: 814 amino acids; 92482 Da

Subunit: Component of the eukaryotic translation initiation factor 3 (eIF-3) complex, which is composed of 13

subunits: EIF3A, EIF3B, EIF3C, EIF3D, EIF3E, EIF3F, EIF3G, EIF3H, EIF3I, EIF3J, EIF3K, EIF3L and EIF3M. The eIF-3

complex appears to include 3 stable modules: module A is composed of EIF3A, EIF3B, EIF3G and EIF3I; module B is

composed of EIF3F, EIF3H, and EIF3M; and module C is composed of EIF3C, EIF3D, EIF3E, EIF3K and EIF3L. EIF3C of

module C binds EIF3B of module A and EIF3H of module B, thereby linking the three modules. EIF3J is a labile

subunit that binds to the eIF-3 complex via EIF3B. The eIF-3 complex interacts with RPS6KB1 under conditions of

nutrient depletion. Mitogenic stimulation leads to binding and activation of a complex composed of MTOR and

RPTOR, leading to phosphorylation and release of RPS6KB1 and binding of EIF4B to eIF-3. Also interacts with UPF2
