**Background of CENPJ Recombinant Protein**
CENPJ (Centromere Protein J), also known as CPAP (Centrosomal P4.1-associated protein), is a critical regulator of centrosome and centriole biogenesis. It plays a central role in maintaining genomic stability by ensuring accurate centrosome duplication, microtubule organization, and mitotic spindle formation during cell division. Structurally, CENPJ contains multiple domains, including a microtubule-binding domain and a conserved C-terminal region essential for centriole elongation. Dysregulation of CENPJ is linked to microcephaly, primordial dwarfism, and cancer, highlighting its importance in cellular and developmental processes.
Recombinant CENPJ protein is engineered using expression systems like *E. coli* or mammalian cells, often tagged with affinity markers (e.g., His-tag) for purification. This tool enables researchers to study CENPJ’s interactions with partners such as γ-tubulin, STIL, and SAS-6. which are vital for centriole assembly. *In vitro* studies with recombinant CENPJ help dissect its role in microtubule nucleation, centriole length control, and cell cycle regulation. Additionally, it serves as an antigen for antibody development or a reference in functional assays to investigate disease-associated mutations (e.g., MCPH6. a microcephaly-linked autosomal recessive disorder).
Therapeutic research leverages recombinant CENPJ to explore pathways underlying developmental disorders and cancer, where centrosome amplification is common. By analyzing its structure-function relationships, scientists aim to design targeted therapies to correct centrosomal defects or inhibit tumor growth. Overall, CENPJ recombinant protein is a pivotal resource for advancing our understanding of cell division mechanics and related pathologies.
