Aspm Gene Summary [Rat]
Predicted to enable calmodulin binding activity. Predicted to be involved in regulation of meiotic cell cycle; spindle localization; and spindle organization. Predicted to act upstream of or within several processes, including maintenance of centrosome location; nervous system development; and neuronal stem cell population maintenance. Located in apical plasma membrane; microtubule cytoskeleton; and midbody. Human ortholog(s) of this gene implicated in primary autosomal recessive microcephaly and primary autosomal recessive microcephaly 5. Orthologous to human ASPM (assembly factor for spindle microtubules). [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 Aspm often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
