Summary
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. Is expressed in cerebral cortex ventricular layer. 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). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
