**Background of CEP63 Recombinant Protein**
CEP63 (Centrosomal Protein 63) is a critical component of the centrosome, a microtubule-organizing center essential for cell division, cytoskeletal organization, and cilia formation. Structurally, CEP63 contains conserved coiled-coil domains that mediate interactions with other centrosomal proteins, such as CEP152. forming a scaffold required for centrosome duplication. This protein plays a pivotal role in maintaining genomic stability by ensuring proper centrosome number and function during the cell cycle. Dysregulation of CEP63 has been linked to microcephaly, a neurodevelopmental disorder characterized by reduced brain size, as well as cancer progression due to mitotic errors.
Recombinant CEP63 protein is engineered using molecular cloning techniques, where the CEP63 gene is expressed in heterologous systems like *E. coli* or mammalian cells (e.g., HEK293). This allows large-scale production of the protein with high purity, often tagged with markers such as His or GST for purification and detection. Recombinant CEP63 serves as a vital tool for studying centrosome biology, protein-protein interactions (e.g., with CEP152 or PLK4), and mechanisms underlying diseases. It is also used in functional assays, such as in vitro binding studies, cellular rescue experiments in CEP63-deficient models, and screening for therapeutic compounds targeting centrosome-related pathologies. The availability of recombinant CEP63 accelerates research into mitotic regulation and potential treatments for microcephaly or cancer.
