Gene Symbol Lalba
Protein Name lactalbumin, alpha
Synonyms AW208827;
Species Mus musculus
Ensembl Protein ENSMUSP00000023726
InnateDB Gene IDBG-180342 (Lalba)
Protein Structure
UniProt Annotation
Function Regulatory subunit of lactose synthase, changes the substrate specificity of galactosyltransferase in the mammary gland making glucose a good acceptor substrate for this enzyme. This enables LS to synthesize lactose, the major carbohydrate component of milk. In other tissues, galactosyltransferase transfers galactose onto the N-acetylglucosamine of the oligosaccharide chains in glycoproteins.
Subcellular Localization Secreted.
Disease Associations
Tissue Specificity Mammary gland specific. Secreted in milk.
