Eukaryotic translation initiation factor 4B is a protein that in humans is encoded by the EIF4B gene.^[1]

Interactions

EIF4B has been shown to interact with EIF3A.^[2]

There is increasing evidence to suggest that microRNAs (miRNAs; miRs) are involved in the development of oral squamous cell carcinoma (OSCC). miR‑216a has been identified as being involved in tumorigenesis, however, the mechanisms of miR‑216a in various types of cancer, either as a tumor suppres

Kaposi's sarcoma-associated herpesvirus (KSHV) encodes multiple viral proteins that activate extracellular signal-regulated kinase (ERK)-mitogen-activated protein kinase (MAPK) cascades. One of these viral proteins, ORF45, mediates sustained ERK-p90 ribosomal S6 kinase (RSK) activation during KSHV l

Spinocerebellar ataxia type 2 (SCA2) and amyotrophic lateral sclerosis (ALS) are neurodegenerative disorders, caused or modified by an unstable CAG-repeat expansion in the SCA2 gene, which encodes a polyglutamine (polyQ) domain expansion in ataxin-2 (ATXN2). ATXN2 is an RNA-binding protein and inter
