Eukaryotic translation initiation factor 4H

eIF4H, WSCR1, WBSCR1, heIF4H, eukaryotic translation initiation factor 4H
This gene encodes one of the translation initiation factors, which functions to stimulate the initiation of protein synthesis at the level of mRNA utilization. This gene is deleted in Williams syndrome, a multisystem developmental disorder caused by the deletion of contiguous genes at 7q11.23. Alternative splicing of this gene generates 2 transcript variants. [provided by RefSeq, Jul 2008] (from NCBI)
Top mentioned proteins: eIF4B, CAN, eIF4E, caspase-3, LIMK1

New
Touriol et al., Toulouse, France. In Oncotarget, Dec 2015
Here we show that eIF4H (eukaryotic translation initiation factor 4H), an activator of the RNA helicase eIF4A, is overexpressed in lung carcinomas and predictive of response to chemotherapy.

Identification of the responsible proteins for increased selenium bioavailability in the brain of transgenic rats overexpressing selenoprotein M.
Seong et al., Seoul, South Korea. In Int J Mol Med, 2014
The results revealed that: ⅰ) CMV/hSelM Tg rats showed a high level of enzyme activity for antioxidant protein in the brain cortex compared to non-Tg rats; ⅱ) the high activity of these enzymes induced a decrease in total antioxidant concentration and γ-secretase activity in CMV/hSelM Tg rats; ⅲ) five proteins were upregulated and three were downregulated by SelM overexpression; ⅳ) among the five upregulated proteins, two associated with creatine kinase B-type (B-CK) and E3 ubiquitin-protein ligase RING1 (RING finger protein 1) were further increased in the two groups following Sel treatment, whereas synaptotagmin-15 (SytXV), eukaryotic translation initiation factor 4H (eIF-4H) and lactate dehydrogenase B (LDH-B) were increased or decreased under the same conditions; ⅴ) the three downregulated proteins did not induce a significant change in expression following Sel treatment; and ⅵ) the protein expression level alterations of the two selected spots (B-CK and SytXV) identified by 2-DE were extremely similar to the results from western blot analysis.
Single-molecule kinetics of the eukaryotic initiation factor 4AI upon RNA unwinding.
Meller et al., Boston, United States. In Structure, 2014
Previous studies demonstrated that eIF4AI, in conjunction with eIF4H, bind to loop structures and repetitively unwind RNA hairpins.
Drosha promotes splicing of a pre-microRNA-like alternative exon.
Hastings et al., Lake Forest, United States. In Plos Genet, 2014
We find that Drosha can cleave the alternatively spliced exon 5 of the eIF4H gene into a pre-miRNA both in vitro and in cells.
mRNA decay during herpes simplex virus (HSV) infections: mutations that affect translation of an mRNA influence the sites at which it is cleaved by the HSV virion host shutoff (Vhs) protein.
Read et al., Kansas City, United States. In J Virol, 2013
Vhs binds the translation initiation factors eIF4H, eIF4AI, and eIF4AII, suggesting that its mRNA degradative function is somehow linked to translation.
Eukaryotic Initiation Factor 4H Is under Transcriptional Control of p65/NF-κB.
Quinto et al., Catanzaro, Italy. In Plos One, 2012
We show that the p65 subunit of NF-κB activates the transcription of eIF4H gene, which is the regulatory subunit of eIF4A, the most relevant RNA helicase in translation initiation.
The eukaryotic initiation factor eIF4H facilitates loop-binding, repetitive RNA unwinding by the eIF4A DEAD-box helicase.
Meller et al., Boston, United States. In Nucleic Acids Res, 2012
Single molecule fluorescence resonance energy transfer (sm-FRET) is applied here to directly observe and quantify the helicase activity of eIF4AI in the presence of the ancillary RNA-binding factor eIF4H. Results show that eIF4H can significantly enhance the helicase activity of eIF4AI by strongly binding both to loop structures within the RNA transcript as well as to eIF4AI.
