Supplementary information

CENPA also known as Centromere Protein A is an essential component of the centromere specifically during cell division. It represents a histone H3 variant with an approximate mass of 17 kDa. This protein is expressed at the centromere regions of chromosomes where it substitutes conventional histone H3. CENPA facilitates the assembly of the kinetochore an important structure for chromosome segregation. Scientists also refer to this protein as CENP-A often in conjunction with studies involving anti-centromere antibodies and centromere staining.
Biological function summary

CENPA plays a central role in accurate chromosome segregation during mitosis and meiosis. It incorporates into nucleosomes at the centromere replacing standard histone H3 to promote kinetochore formation. CENPA is part of a larger protein complex known as the centromere. This complex propelled by CENPA drives proper attachment of chromosomes to spindle microtubules preventing aneuploidy.

Pathways

The kinetochore pathway and the chromosome segregation pathway both involve CENPA significantly. It functions in tandem with other centromeric proteins such as CENP-B and CENP-C which work collaboratively to sustain centromere integrity. CENPA interacts with these proteins to orchestrate correct alignment and separation of chromosomes integrating it into the foundational architecture of genetic stability.

CENPA has association with several chromosomal instability syndromes. Misregulation or mutation of this protein may contribute to cancer progression where improper chromosome segregation is an important factor. It also connects to other proteins like CENP-H implicated in malignancies due to errors in chromosome transmission. Additionally autoimmune diseases often involve centromere antibodies highlighting the connection of CENPA to disorders such as systemic sclerosis.

Target data

Histone H3-like nucleosomal protein that is specifically found in centromeric nucleosomes (PubMed : 11756469, PubMed : 14667408, PubMed : 15282608, PubMed : 15475964, PubMed : 15702419, PubMed : 17651496, PubMed : 19114591, PubMed : 20739937, PubMed : 27499292, PubMed : 7962047, PubMed : 9024683). Replaces conventional H3 in the nucleosome core of centromeric chromatin that serves as an assembly site for the inner kinetochore (PubMed : 18072184). The presence of CENPA subtly modifies the nucleosome structure and the way DNA is wrapped around the nucleosome and gives rise to protruding DNA ends that are less well-ordered and rigid compared to nucleosomes containing histone H3 (PubMed : 26878239, PubMed : 27499292). May serve as an epigenetic mark that propagates centromere identity through replication and cell division (PubMed : 15282608, PubMed : 15475964, PubMed : 20739937, PubMed : 21478274, PubMed : 26878239). Required for recruitment and assembly of kinetochore proteins, and as a consequence required for progress through mitosis, chromosome segregation and cytokinesis (PubMed : 11756469, PubMed : 14667408, PubMed : 18072184, PubMed : 23818633, PubMed : 25556658, PubMed : 27499292).
