About LDHB

Cytogenetic location: 12p12.1 Genomic coordinates (GRCh38): 12:21,635,342-21,657,842 (from NCBI)

This gene has 11 transcripts (splice variants), 279 orthologues, 5 paralogues and is associated with 2 phenotypes. Broad expression in kidney (RPKM 475.5), heart (RPKM 454.7) and 21 other tissues.

Summary

This gene encodes the B subunit of Lactate Dehydrogenase enzyme, which catalyzes the interconversion of pyruvate and lactate with concomitant interconversion of NADH and NAD+ in a post-glycolysis process. Alternatively spliced transcript variants have been found for this gene. Recent studies have shown that a C-terminally extended isoform is produced by use of an alternative in-frame translation termination codon via a stop codon readthrough mechanism, and that this isoform is localized in the peroxisomes. Mutations in this gene are associated with Lactate Dehydrogenase B deficiency. Pseudogenes have been identified on chromosomes X, 5 and 13. [provided by RefSeq, Feb 2016]
