Protein attributes

Sequence length	398 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	The Golgi complex form catalyzes the production of lactose in the lactating mammary gland and could also be responsible for the synthesis of complex-type N-linked oligosaccharides in many glycoproteins as well as the carbohydrate moieties of glycolipids. The cell surface form functions as a recognition molecule during a variety of cell to cell and cell to matrix interactions, as those occurring during development and egg fertilization, by binding to specific oligosaccharide ligands on opposing cells or in the extracellular matrix.
Catalytic activity	UDP-alpha-D-galactose + D-glucose = UDP + lactose. UDP-alpha-D-galactose + N-acetyl-beta-D-glucosaminylglycopeptide = UDP + beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminylglycopeptide. UDP-alpha-D-galactose + N-acetyl-D-glucosamine = UDP + N-acetyllactosamine.
Cofactor	Manganese By similarity.
Pathway	Protein modification; protein glycosylation.
Subunit structure	Homodimer; and heterodimer with alpha-lactabulmin to form lactose synthase. Ref.14
Subcellular location	Isoform Long: Golgi apparatus › Golgi stack membrane; Single-pass type II membrane protein. Cell membrane; Single-pass type II membrane protein. Cell surface. Note: Found in trans cisternae of Golgi. Ref.13 Isoform Short: Golgi apparatus › Golgi stack membrane; Single-pass type II membrane protein. Note: Found in trans cisternae of Golgi. Ref.13 Processed beta-1,4-galactosyltransferase 1: Secreted. Note: Soluble form found in body fluids. Ref.13
Tissue specificity	Ubiquitously expressed, but at very low levels in fetal and adult brain.
Post-translational modification	The soluble form derives from the membrane forms by proteolytic processing.
Involvement in disease	Congenital disorder of glycosylation 2D (CDG2D) [MIM:607091]: A multisystem disorder caused by a defect in glycoprotein biosynthesis and characterized by under-glycosylated serum glycoproteins. Congenital disorders of glycosylation result in a wide variety of clinical features, such as defects in the nervous system development, psychomotor retardation, dysmorphic features, hypotonia, coagulation disorders, and immunodeficiency. The broad spectrum of features reflects the critical role of N-glycoproteins during embryonic development, differentiation, and maintenance of cell functions. Note: The disease is caused by mutations affecting the gene represented in this entry.
Sequence similarities	Belongs to the glycosyltransferase 7 family.
