GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. cnp3-1 mutant is prone to promiscuous accumulation of Cnp1 at non-centromeric regions. Cnp3 plays a role in restricting the site of accumulation of Cnp1 and thus prevents formation of de novo centromeres.
    Title: Fission Yeast CENP-C (Cnp3) Plays a Role in Restricting the Site of CENP-A Accumulation.
  2. Residues 26-50 in Cnp3 are responsible for interacting with the Mis12 complex. Cnp3 is a substrate of Ark1 and phosphorylation impairs the interaction between the Cnp3 and Mis12 complex.
    Title: Phosphorylation of CENP-C by Aurora B facilitates kinetochore attachment error correction in mitosis.
  3. CENP-C serves as a scaffold for the specific recruitment of essential kinetochore proteins
    Title: CENP-C functions as a scaffold for effectors with essential kinetochore functions in mitosis and meiosis.
