Gmppa Gene Summary [Rat]
Predicted to enable enzyme binding activity; enzyme inhibitor activity; and molecular sensor activity. Predicted to be involved in negative regulation of metabolic process. Predicted to act upstream of or within several processes, including GDP-mannose biosynthetic process; motor behavior; and protein glycosylation. Predicted to be part of GDP-mannose pyrophosphorylase complex. Predicted to be active in cytoplasm. Human ortholog(s) of this gene implicated in alacrima, achalasia, and impaired intellectual development syndrome. Orthologous to human GMPPA (GDP-mannose pyrophosphorylase A).

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