Gene Summary
Centromeric protein-C (Cenp-C) encodes an essential centromere protein. It binds to the product of cid and provides a binding site for the Mis12 kinetochore protein complex, which is recruited to the centromere at the start of mitotic and meiotic M phases. It also binds the product of cal1, which is crucial for propagation of the epigenetic mark that specifies centromere identity during progression through the cell division cycle.

    Model Confidence:
    • Very high (pLDDT > 90)
    • Confident (90 > pLDDT > 70)
    • Low (70 > pLDDT > 50)
    • Very low (pLDDT < 50)

    AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

        RNAi screen using dsRNA made from templates generated with primers directed against this gene results in chromosome misalignment on the metaphase spindle, the formation of aberrantly long spindles and pole detachment when assayed in S2 cells. This phenotype can be observed when the screen is performed with or without Cdc27 dsRNA.

        New incorporation of Cenp-C protein into centromeres takes place during anaphase of the syncytial divisions of embryos. This incorporation is independent of DNA replication and of normal pulling forces generated by the mitotic spindle, but is strictly coupled to mitotic progression.

        RNAi generated by PCR using primers directed to this gene causes a cell growth and viability phenotype when assayed in Kc167 and S2R+ cells.

        1 allele of l(3)SH157 recovered in a P-insertion screen.
