Summary
Enables microtubule plus end polymerase; plus-end-directed microtubule motor activity; and tubulin binding activity. Involved in microtubule polymerization; negative regulation of microtubule depolymerization; and nuclear migration along microtubule. Located in cortical microtubule plus-end and spindle pole body. Human ortholog(s) of this gene implicated in primary autosomal recessive microcephaly 13. Orthologous to human CENPE (centromere protein E). [provided by Alliance of Genome Resources, Jul 2025]
