Spag5 Gene Summary [Rat]
Predicted to enable microtubule binding activity. Predicted to be involved in several processes, including protein localization to centrosome; regulation of cell cycle process; and regulation of metaphase plate congression. Predicted to act upstream of or within establishment of spindle orientation. Predicted to be located in several cellular components, including cytoskeleton; kinetochore; and nuclear body. Orthologous to human SPAG5 (sperm associated antigen 5). [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 Spag5 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
