TGM5 Gene

TGM5 (transglutaminase 5) is a protein-coding gene located on chromosome 15q15.2. Diseases associated with TGM5 include peeling skin syndrome. Associated metabolic pathways include developmental biology and keratinization.

This gene encodes a member of the transglutaminase family. The encoded protein catalyzes the formation of protein crosslinks between glutamine and lysine residues, often leading to stabilization of protein assemblies. This reaction is calcium dependent.

Numerous mutations in this gene have been associated with acral peeling syndrome, a suprabasal epidermolysis bullosa simplex (Szczecinska W et al. 2014).
