General annotation (Comments)
| Function | Histone H3-like variant which exclusively replaces conventional H3 in the nucleosome core of centromeric chromatin at the inner plate of the kinetochore. Required for recruitment and assembly of kinetochore proteins, mitotic progression and chromosome segregation. May serve as an epigenetic mark that propagates centromere identity through replication and cell division. Ref.6 Ref.9 |
| Subunit structure | Forms a nucleosome-like histone octamer containing two molecules each of H2A, H2B, cid and H4 assembled in one cid-H4 heterotetramer and two H2A-H2B heterodimers. The cid-H4 heterotetramer is more compact and structurally more rigid than corresponding H3-H4 heterotetramers By similarity. Interacts with the condensin subunit Cap-G. Ref.8 |
| Subcellular location | Nucleus. Centromere. Kinetochore. Note: Localizes exclusively in the kinetochore domain of centromeres. Ref.1 Ref.7 |
| Sequence similarities | Belongs to the histone H3 family. |
| Sequence caution | The sequence AAM75058.1 differs from that shown. Reason: Frameshift at position 86. |
