Centromere protein J (CENPJ)

Plays an important role in cell division and centrosome function by engaging in centriole duplication (PubMed:17681131, PubMed:20531387). Inhibits microtubule nucleation from the centrosome.

Involved in the regulation of slow processive growth of centriolar microtubules. Acts as microtubule plus-end monitoring protein that stabilizes centriolar microtubules and inhibits microtubule polymerization and expansion from the distal ends of centrioles (PubMed:15047868, PubMed:27219064, PubMed:27306797).
