Tgm1 Gene Summary [Rat]
Predicted to enable identical protein binding activity and protein-glutamine gamma-glutamyltransferase activity. Predicted to be involved in several processes, including keratinocyte differentiation; peptide cross-linking; and positive regulation of keratinocyte proliferation. Predicted to act upstream of or within animal organ morphogenesis. Predicted to be located in adherens junction and membrane. Human ortholog(s) of this gene implicated in autosomal recessive congenital ichthyosis 1. Orthologous to human TGM1 (transglutaminase 1). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Tgm1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
