About EIF2B4

Cytogenetic location: 2p23.3 Genomic coordinates (GRCh38): 2:27,364,352-27,370,338 (from NCBI)

This gene has 10 transcripts (splice variants), 206 orthologues, 3 paralogues and is associated with 7 phenotypes. Ubiquitous expression in testis (RPKM 20.0), prostate (RPKM 13.7) and 25 other tissues.

Summary

Eukaryotic initiation factor 2B (EIF2B), which is necessary for protein synthesis, is a GTP exchange factor composed of five different subunits. The protein encoded by this gene is the fourth, or delta, subunit. Defects in this gene are a cause of leukoencephalopathy with vanishing white matter (VWM) and ovarioleukodystrophy. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
