MGI Phenotype FUNCTION: This gene encodes two distinct enzyme isoforms, a long membrane-bound form and a short soluble form. These alternate isoforms are thought to be produced through alternative nested transcription initiation and different in-frame start codon usage. These enzymes catalyze the transfer of galactose to acceptor sugars, such as N-acetylglucosamine and glucose. The long form of this enzyme is localized to the trans-Golgi membrane and is involved in glycoconjugate biosynthesis. The short form functions in lactose biosynthesis though formation of a heterodimer with alpha-lactalbumin. [provided by RefSeq, Nov 2012]
PHENOTYPE: Homozygotes for targeted null mutations exhibit growth retardation, low viability, excessive epithelial cell proliferation of skin and small intestine, sperm with reduced fertilizing capacity, birthing difficulty, and mammary gland defects. [provided by MGI curators]
