pH: 8.00 Constituents: 0.31% Glutathione, 0.79% Tris HCl
Protein glutamine gamma glutamyltransferase K
Protein-glutamine gamma-glutamyltransferase K
Transglutaminase 1 (K polypeptide epidermal type I, protein glutamine gamma glutamyltransferase)
Catalyzes the cross-linking of proteins and the conjugation of polyamines to proteins. Responsible for cross-linking epidermal proteins during formation of the stratum corneum.
Involvement in disease
Defects in TGM1 are the cause of ichthyosis lamellar type 1 (LI1) [MIM:242300]. LI is a non-bullous ichthyosis, a skin disorder characterized by abnormal cornification of the epidermis. It is one the most severe forms of ichthyoses apparent at birth and persisting throughout life. LI patients are born encased in a tight, shiny, translucent covering called collodion membrane. Over the first weeks of life, the collodion membrane is gradually replaced by generalized large, dark brown, plate-like scales with minimal to no erythroderma. Tautness of facial skin commonly results in ectropion, eclabium and scarring alopecia of the scalp. Common complications are severe heat intolerance and recurrent ear infections. Defects in TGM1 are a cause of non-bullous congenital ichthyosiform erythroderma (NCIE) [MIM:242100]. NCIE is a non-bullous ichthyosis, a skin disorder characterized by abnormal cornification of the epidermis. Most affected individuals are born with a tight, shiny, translucent covering called collodion membrane. The collodion membrane subsequently evolves into generalized scaling and intense redness of the skin. Clinical features are milder than in lamellar ichthyoses and demonstrate a greater variability in the intensity of erythema, size and type of scales. In contrast to lamellar ichthyoses, scales are usually white, fine and powdery, and palms and soles are severely affected. Patients suffer from palmoplantar keratoderma, often with painful fissures, digital contractures, and loss of pulp volume. Defects in TGM1 are the cause of ichthyosis congenital autosomal recessive TGM1-related (ARCI-TGM1) [MIM:242300]. A disorder of keratinization with abnormal differentiation and desquamation of the epidermis resulting in two major clinical entities. Lamellar ichthyosis is a condition often associated with an embedment in a collodion-like membrane at birth; skin scales later develop, covering the entire body surface. Non-bullous congenital ichthyosiform erythroderma characterized by fine whitish scaling on an erythrodermal background; larger brownish scales are present on the buttocks, neck and legs.
Belongs to the transglutaminase superfamily. Transglutaminase family.
The membrane anchorage region possesses a cluster of five cysteines within which fatty acid(s) may become thioester-linked. It is subject to phorbol ester-stimulated phosphorylation and is hypersensitive to proteolysis, which releases the enzyme in a soluble form.
