Knstrn Gene Summary [Rat]
Predicted to enable microtubule plus-end binding activity and protein homodimerization activity. Predicted to be involved in several processes, including cellular response to epidermal growth factor stimulus; mitotic sister chromatid segregation; and regulation of attachment of spindle microtubules to kinetochore. Predicted to be located in microtubule organizing center; plasma membrane; and ruffle. Predicted to be active in kinetochore and microtubule cytoskeleton. Human ortholog(s) of this gene implicated in actinic keratosis and skin squamous cell carcinoma. Orthologous to human KNSTRN (kinetochore localized astrin (SPAG5) binding protein).

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