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 pre- initiation 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 (PubMed:17581632). The eIF- 3 complex specifically targets and initiates translation of a subset of mRNAs involved in cell proliferation, including cell cycling, differentiation and apoptosis, and uses different modes of RNA stem-loop binding to exert either translational activation or repression (PubMed:25849773). {ECO:0000255|HAMAP-Rule:MF_03010, ECO:0000269|PubMed:17581632, ECO:0000269|PubMed:25849773, ECO:0000269|PubMed:27462815}. |SAC3 GANP| |PCI Csn8| |eukaryotic 48S preinitiation complex| |formation of cytoplasmic translation initiation complex| |eukaryotic translation initiation factor 3 complex| |eukaryotic 43S preinitiation complex| |cytoplasmic translational initiation| |translation initiation factor activity| |ribosome binding| |cytoplasmic translation| |regulation of translational initiation| |translational initiation| |ribonucleoprotein complex assembly| |ribonucleoprotein complex subunit organization| |regulation of translation| |translation| |regulation of cellular amide metabolic process| |peptide biosynthetic process| |ribonucleoprotein complex biogenesis| |posttranscriptional regulation of gene expression| |amide biosynthetic process| |peptide metabolic process| |cellular amide metabolic process| |cellular protein-containing complex assembly| |organonitrogen compound biosynthetic process| |protein-containing complex assembly| |cellular nitrogen compound biosynthetic process| |cellular macromolecule biosynthetic process| |macromolecule biosynthetic process| |protein-containing complex subunit organization| |membrane| |gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp515|PU-H71 1μM R08 exp515]]|-2.62| |[[:results:exp30|Rapamycin 10μM R00 exp30]]|-2.12| |[[:results:exp531|THZ1 0.06μM R08 exp531]]|-1.97| |[[:results:exp94|Nocodazole 0.1μM R03 exp94]]|-1.96| |[[:results:exp443|SNS-032 15μM R08 exp443]]|-1.8| |[[:results:exp409|THZ531 0.11μM R07 exp409]]|1.75| |[[:results:exp449|Arsenic trioxide 60μM R08 exp449]]|1.78| |[[:results:exp66|BI-D1870 3.15μM R02 exp66]]|1.79| |[[:results:exp410|THZ531 0.11 to 0.125μM on day4 R07 exp410]]|1.83| |[[:results:exp95|BI-2536 0.0042μM R03 exp95]]|1.84| |[[:results:exp365|I-BRD9 4μM R07 exp365]]|1.84| |[[:results:exp229|Dimethyloxaloylglycine 100μM R05 exp229]]|1.85| |[[:results:exp362|GSK-J4 1μM R07 exp362]]|2.09| |[[:results:exp36|TRAIL 50ng/ml R00 exp36]]|2.42| |[[:results:exp35|TRAIL 5ng/ml R00 exp35]]|2.88| |[[:results:exp416|Tubacin 1.6μM R07 exp416]]|3.19| ^Gene^Correlation^ |[[:human genes:e:eif3l|EIF3L]]|0.657| |[[:human genes:b:bcl2l1|BCL2L1]]|0.461| |[[:human genes:a:atp13a1|ATP13A1]]|0.458| |[[:human genes:s:smg7|SMG7]]|0.43| |[[:human genes:m:mtf1|MTF1]]|0.409| |[[:human genes:r:rpl30|RPL30]]|0.407| Global Fraction of Cell Lines Where Essential: 0/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/26| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|0/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 1641 * **Expression level (log2 read counts)**: 6.87 {{:chemogenomics:nalm6 dist.png?nolink |}}
