EIF2B1 - eukaryotic translation initiation factor 2B subunit alpha Gene

Also Known as EIF2B; EIF2BA; EIF2Balpha

Species: Homo sapiens

Gene Type: protein coding

Gene ID: 1967

About EIF2B1

Cytogenetic location: 12q24.31 Genomic coordinates (GRCh38): 12:123,620,406-123,633,686 (from NCBI)

This gene has 6 transcripts (splice variants), 222 orthologues, 3 paralogues and is associated with 6 phenotypes. Ubiquitous expression in lymph node (RPKM 22.1), skin (RPKM 20.5) and 25 other tissues.

Summary

This gene encodes one of five subunits of eukaryotic translation initiation factor 2B (EIF2B), a GTP exchange factor for eukaryotic initiation factor 2 and an essential regulator for protein synthesis. Mutations in this gene and the genes encoding Other EIF2B subunits have been associated with leukoencephalopathy with vanishing white matter. [provided by RefSeq, Oct 2009]
