Schematic map of reported protein-protein interactions between HJURP, CENP-B, CENP-C, CENP-A, M18BP1, Mis18α and Mis18β. Numbers indicate amino acid (aa) positions for each protein relative to their domains. Specific aa residues are also marked to highlight a particular PTM or interaction. HIKLMN are CENP proteins, CATD = CENP-A targeting domain, HCTD1/2 = HJURP C-terminal domain, SANT-A = SANT associated domain, green and red P = phosphorylation that lead to protein activation or inhibition, respectively. Top left inset: model for new CENP-A deposition based on an interplay of two CENP-C molecules to assemble a new CENP-A nucleosome at the centromere during early G1 phase.
