Eukaryotic initiation factor-3 (EIF3) has a molecular mass of about 600 kD and contains 13 nonidentical protein subunits, including EIF3J. EIF3 plays a central role in binding of initiator methionyl-tRNA and mRNA to the 40S ribosomal subunit to form the 40S initiation complex (Fraser et al., 2004 [PubMed 14688252]; Fraser et al., 2007 [PubMed 17588516]).[supplied by OMIM, Mar 2008] (from NCBI)

Our structure highlights differences in initiation-complex binding to the ribosome compared to that of mammalian eIF3, demonstrates a direct contact between eIF3j and eIF1A and reveals the network of interactions between eIF3 subunits.
Human eukaryotic initiation factor 2 (eIF2)-GTP-Met-tRNAi ternary complex and eIF3 stabilize the 43 S preinitiation complex.
Fraser et al., Davis, United States. In J Biol Chem, 2014
We have reconstituted the human 43 S PIC and used fluorescence anisotropy to systematically measure the affinity of eIF1, eIF1A, and eIF3j in the presence of different combinations of 43 S PIC components.
Functional and biochemical characterization of human eukaryotic translation initiation factor 3 in living cells.
Valášek et al., Praha, Czech Republic. In Mol Cell Biol, 2014

de Melo Neto et al., Recife, Brazil. In Bmc Genomics, 2013
The biochemical data indicates a lack of association of the eIF3j subunit to the complex whilst highlighting the strong interaction between eIF3 and eIF1.
Translation initiation factors eIF3 and HCR1 control translation termination and stop codon read-through in yeast cells.

Here, we uncover roles for HCR1 and eIF3 in translation termination in vivo.
Spectrin domain of eukaryotic initiation factor 3a is the docking site for formation of the a:b:i:g subcomplex.
Zhang et al., Indianapolis, United States. In J Biol Chem, 2013
The binding of eIF3b to the spectrin domain of eIF3a occurs in its RNA recognition motif domain where eIF3j also binds in a mutually exclusive manner.

Components of the multifactor complex needed for internal initiation by the IRES of hepatitis C virus in Saccharomyces cerevisiae.
Racaniello et al., New York City, United States. In Rna Biol, 2010
Internal initiation dependent upon the HCV IRES was abrogated in strains lacking eIF5B, and reduced in strains with altered eIF3, either lacking the Hcr1p subunit, a component of eIF3 not previously known to interact with HCV RNA, or possessing an amino acid change in the Rpg1p subunit.
The C-terminal region of eukaryotic translation initiation factor 3a (eIF3a) promotes mRNA recruitment, scanning, and, together with eIF3j and the eIF3b RNA recognition motif, selection of AUG start codons.
GeneRIF
Hinnebusch et al., Bethesda, United States. In Mol Cell Biol, 2010
Data suggest that the eIF3b-eIF3j/eIF3a module binds near the mRNA entry channel and regulates the transition between scanning-conducive and initiation-competent conformations of the preinitiation complex.
The indispensable N-terminal half of eIF3j/HCR1 cooperates with its structurally conserved binding partner eIF3b/PRT1-RRM and with eIF1A in stringent AUG selection.

although the Fe-S cluster is not required for the interaction of Rli1 with eRF1 or its other interacting partner, Hcr1, from the initiation complex eIF3, it is required for its activity in translation termination
Crystal structure of the RNA recognition motif of yeast translation initiation factor eIF3b reveals differences to human eIF3b.
Ficner et al., Göttingen, Germany. In Plos One, 2009
It harbors an RNA Recognition Motif (RRM), which is shown to be a non-canonical RRM in human as it is not capable to interact with oligonucleotides, but rather interacts with eIF3j, a sub-stoichiometric subunit of eIF3.
