Summary: The 700-kD eukaryotic translation initiation factor-3 (eIF3) is the largest eIF and contains at least 12 subunits, including EIF2S12. eIF3 plays an essential role in translation by binding directly to the 40S ribosomal subunit and promoting formation of the 40S preinitiation complex (Mayeur et al., 2003 [PubMed 14519125]).[supplied by OMIM, Mar 2008]
Expression: Ubiquitous expression in heart (RPKM 136.4), duodenum (RPKM 100.7) and 25 other tissues See more

What's a GeneRIF?

Whereas the eIF3c knockdown reduces it, downregulation of eIF3k or eIF3l increases mRNA recruitment, suggesting that the latter subunits possess a regulatory potential. Altogether this study provides new insights into the role of human eIF3 in the initial assembly steps of the translational machinery
Title: Adapted formaldehyde gradient cross-linking protocol implicates human eIF3d and eIF3c, k and l subunits in the 43S and 48S pre-initiation complex assembly, respectively.
eIF3K subunit interacts directly with the PML protein.
Title: The translation initiation factor 3 subunit eIF3K interacts with PML and associates with PML nuclear bodies.
eIF3k, originally identified as the smallest subunit of eukaryotic translation initiation factor 3 (eIF3) complexes, also localizes to keratin intermediate filaments and physically associates with K18 in epithelial cells.
Title: eIF3k regulates apoptosis in epithelial cells by releasing caspase 3 from keratin-containing inclusions.
eIF3k has three putative protein-binding surfaces and has potential RNA binding activity
Title: Crystal structure of human eIF3k, the first structure of eIF3 subunits.
cyclin D3 specifically interacted with eIF3k through its C-terminal domain; eIF3k distributed both in nucleus and cytoplasm and colocalized with cyclin D3
Title: Identification of the p28 subunit of eukaryotic initiation factor 3(eIF3k) as a new interaction partner of cyclin D3.
identification of a novel 24-kDa protein that binds directly to dynein intermediate chain [PLAC-24]
Title: PLAC-24 is a cytoplasmic dynein-binding protein that is recruited to sites of cell-cell contact.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
