Hdc Gene Summary [Rat]
Enables several functions, including histidine decarboxylase activity; identical protein binding activity; and pyridoxal phosphate binding activity. Involved in L-histidine metabolic process and histamine metabolic process. Located in dendrite and neuronal cell body. Biomarker of rhinitis. Human ortholog(s) of this gene implicated in Gilles de la Tourette syndrome; asthma; and rhinitis. Orthologous to human HDC (histidine decarboxylase).

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 Hdc often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
