EIF4B
Eukaryotic translation initiation factor 4B

Protein Summary
Description
Required for the binding of mRNA to ribosomes. Functions in close association with EIF4-F and EIF4-A. Binds near the 5'-terminal cap of mRNA in presence of EIF-4F and ATP. Promotes the ATPase activity and the ATP-dependent RNA unwinding activity of both EIF4-A and EIF4-F.

Abstract: (show)
Translation initiation in eukaryotes is an early step in protein synthesis, requiring multiple factors to recruit the ribosomal small subunit to the mRNA 5' untranslated region. One such protein factor is the eukaryotic translation initiation factor 4B (eIF4B), which increases the activity of the eIF4A RNA helicase, and is linked to cell survival and proliferation. We report here the protein backbone chemical shift assignments corresponding to the C-terminal 279 residues of human eIF4B. Analysis of the chemical shift values identifies one main helical region in the area previously linked to RNA binding, and confirms that the overall C-terminal region is intrinsically disordered.

The protein product of DOCK3 is highly expressed in neurons and has a role in cell adhesion and neuronal outgrowth through its interaction with the actin cytoskeleton and key cell signaling molecules. The DOCK3 protein is essential for normal cell growth and migration. Biallelic variants in DOCK3 associated with complete or partial loss of function of the gene were recently reported in six patients with intellectual disability and muscle hypotonia. Only one of the reported patients had congenital malformations outside of the CNS. Further studies are necessary to better determine the prevalence of DOCK3-associated neurodevelopmental disorders and the frequency of non-CNS clinical manifestations in these patients. Since deficiency of the DOCK3 protein product is now an established pathway of this neurodevelopmental condition, supplementing the deficient gene product using a gene therapy approach may be an efficient treatment strategy.

Testicular seminoma is a relatively rare tumor which is mostly detected in male population aged from 15 to 35 years old. Although several molecular biomarkers have been identified to be associated with testicular seminoma pathogenesis, the exact mechanism for testicular seminoma progression remains largely unknown. CDKN2A interacting protein (CDKN2AIP) has previously been identified as a tumor suppressor in multiple malignant diseases. In this study, we aimed to further explore its role in testicular seminoma as well as the underlying molecular mechanisms. Retrospective testicular seminoma clinical samples, normal tissues, NTERA-2 cell line, and mouse xenograft models were used in this study. RT-qPCR, western blot analysis, immunofluorescence microscopy, Co-IP and IP-MS experiments were performed to detect the expression of CDKN2AIP and its interaction with CARM1 and eIF4β. SA-β-gal staining assay and H3K9me3 activity experiments were used to subsequently evaluate the cell senescence and apoptosis. Mouse xenograft animal model was used for in vivo study. The results showed that CDKN2AIP is highly expressed in normal testis samples, and is significantly suppressed in testicular seminoma clinical samples and cell line model. Up-regulation of CDKN2AIP is significantly associated with the inhibition of testicular seminoma tumor growth and the increase of cell senescence and apoptosis. CDKN2AIP exhibits anti-tumor activity by interacting with CARM1 and eIF4β. CDKN2AIP induces testicular seminoma cell senescence by suppressing CARM1 expression and eIF4β phosphorylation. The CDKN2AIP-CARM1 and CDKN2AIP-eIF4β interactions, which induce tumor cell senescence and apoptosis, may be the potential druggable molecular pathways in testicular seminoma tumor pathogenesis and progression.

ATF4 is a crucial transcription factor in the integrated stress response, a major adaptive signaling pathway activated by tumor microenvironment and therapeutic stresses. BRAF inhibitors, such as vemurafenib, induce ATF4 in BRAF-mutated melanoma cells, but the mechanisms of ATF4 induction are not fully elucidated. Here, we show that ATF4 expression can be upregulated by eukaryotic initiation factor 4B (eIF4B) in BRAF-mutated A375 cells. Indeed, eIF4B knockout (KO) prevented ATF4 induction and activation of the uORF-mediated ATF4 translation mechanism during vemurafenib treatment, which were effectively recovered by the rescue of eIF4B. Transcriptome analysis revealed that eIF4B KO selectively influenced ATF4-target gene expression among the overall gene expression changed by vemurafenib. Interestingly, eIF4B supported cellular proliferation under asparagine-limited conditions, possibly through the eIF4B-ATF4 pathway. Our findings indicate that eIF4B can regulate ATF4 expression, thereby contributing to cellular stress adaptation, which could be targeted as a therapeutic approach against malignancies, including melanoma.

Interactome maps are valuable resources to elucidate protein function and disease mechanisms. Here, we report on an interactome map that focuses on neurodegenerative disease (ND), connects ∼5,000 human proteins via ∼30,000 candidate interactions and is generated by systematic yeast two-hybrid interaction screening of ∼500 ND-related proteins and integration of literature interactions. This network reveals interconnectivity across diseases and links many known ND-causing proteins, such as α-synuclein, TDP-43, and ATXN1, to a host of proteins previously unrelated to NDs. It facilitates the identification of interacting proteins that significantly influence mutant TDP-43 and HTT toxicity in transgenic flies, as well as of ARF-GEP100 that controls misfolding and aggregation of multiple ND-causing proteins in experimental model systems. Furthermore, it enables the prediction of ND-specific subnetworks and the identification of proteins, such as ATXN1 and MKL1, that are abnormally aggregated in postmortem brains of Alzheimer's disease patients, suggesting widespread protein aggregation in NDs.
