eukaryotic translation initiation factor 4H stimulates protein translation. May stimulate the activities of EIF4A, EIF4B and EIF4F during the steps involving mRNA binding and utilization in the initiation of protein biosynthesis. Binds mRNA. Two alternatively spliced isoforms have been described. The short isoform is the predominant isoform and is expressed alone in liver and skeletal muscle. Both isoforms are expressed in fibroblast, spleen, testis and bone marrow. Levels are high in lung and pancreas and low in heart, frontal cortex and kidney. Note: This description may include information from UniProtKB.
