MGI Phenotype FUNCTION: 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 also 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. Pseudogenes have been identified on chromosomes 1 and 19. [provided by RefSeq, Feb 2016]
PHENOTYPE: Electrophoretic variants of LDHB are determined by: the a allele with fast anodal mobility in all inbred strains tested; and the b allele with slower mobility in Peru-Coppock stock. Three additional variants are known in wild M. spretus from southern France and Spain. Alleles are codominant. [provided by MGI curators]
