Supplementary information

HJURP also known as Holliday junction recognition protein plays an important mechanical role in chromatin assembly. This protein weighs approximately 82 kDa and coordinates the correct loading of CENP-A at the centromeres during S phase and early G1 phase of the cell cycle. HJURP is mostly expressed in proliferative tissues and cell lines reflecting its involvement in processes requiring accurate chromosomal segregation during cell division. Its presence ensures that centromere identity is passed onto the daughter cells.

Biological function summary

HJURP is critical for centromere function and stability. It operates by forming a complex with centromere protein A (CENP-A) which completes the assembly and maintenance of centromere chromatin. HJURP achieves this by acting as a chaperone specifically ensuring the accurate deposition of CENP-A at the centromeres. The functionality of HJURP within this complex highlights its role in sustaining genomic integrity throughout cell division processes.

Pathways

HJURP lies at the center of the centromere-specific chromatin assembly pathway. This pathway is essential for the replenishment of centromeric CENP-A thereby ensuring accurate chromosome segregation. HJURP interacts significantly with other proteins such as CALM and H4 aiding in chromatin dynamics and stability. These interactions help integrate HJURP's actions into larger cellular and genetic processes particularly those involving DNA replication and cell cycle progression.

HJURP links closely to cancerous transformations and chromosomal instability disorders. Abnormal expression or mutations of HJURP can disrupt centromere function potentially leading to aneuploidy—a condition often found in various cancers. Its association with other proteins such as HJURP's interaction with overexpressed CENP-A in these pathological states highlights its significance in maintaining cellular health. Therefore HJURP emerges as a potential biomarker for these conditions and warrants further research into therapeutic interventions.

Target data

Centromeric protein that plays a central role in the incorporation and maintenance of histone H3-like variant CENPA at centromeres. Acts as a specific chaperone for CENPA and is required for the incorporation of newly synthesized CENPA molecules into nucleosomes at replicated centromeres. Prevents CENPA-H4 tetramerization and prevents premature DNA binding by the CENPA-H4 tetramer. Directly binds Holliday junctions.
