Centromere protein O

Gene

Cenpo

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Experimental evidence at transcript leveli

Functioni

Component of the CENPA-CAD (nucleosome distal) complex, a complex recruited to centromeres which is involved in assembly of kinetochore proteins, mitotic progression and chromosome segregation. May be involved in incorporation of newly synthesized CENPA into centromeres via its interaction with the CENPA-NAC complex. Modulates the kinetochore-bound levels of NDC80 complex (By similarity).By similarity
