Chmp1a Gene Summary [Rat]
Predicted to enable protein domain specific binding activity and protein homodimerization activity. Predicted to be involved in several processes, including midbody abscission; regulation of cell cycle process; and vacuolar transport. Predicted to act upstream of or within mitotic chromosome condensation and negative regulation of gene expression. Predicted to be located in several cellular components, including bounding membrane of organelle; microtubule cytoskeleton; and nuclear lumen. Predicted to be part of ESCRT III complex and nuclear pore. Predicted to be active in multivesicular body. Human ortholog(s) of this gene implicated in pontocerebellar hypoplasia type 8. Orthologous to human CHMP1A (charged multivesicular body protein 1A). [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 Chmp1a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
