PCM1 (Pericentriolar Material 1) is a centrosome-associated protein critical for maintaining the structural and functional integrity of centriolar satellites—dynamic protein complexes surrounding the centrosome. It plays a pivotal role in centrosome maturation, ciliogenesis, and microtubule organization, thereby influencing cell division, polarity, and intracellular transport. PCM1 interacts with multiple proteins, including dynein motors, to regulate the trafficking of centrosomal components, and its dysfunction has been linked to ciliopathies, neurodevelopmental disorders, and cancer.
Recombinant PCM1 protein is engineered using expression systems (e.g., E. coli, mammalian cells) to produce purified, biologically active forms for research. This involves cloning the PCM1 gene into expression vectors, followed by transfection, protein synthesis, and affinity chromatography-based purification (e.g., His-tag or GST-tag systems). The recombinant protein retains functional domains, enabling in vitro studies on its interactions with binding partners (e.g., BBS4. Cep290) and its role in centrosomal clustering or ciliary assembly.
Researchers utilize PCM1 recombinant protein to investigate mechanisms underlying primary cilia formation, mitotic errors, and diseases like Joubert syndrome or glioblastoma. It also serves as an antigen for antibody development or a control in diagnostic assays. Recent studies highlight PCM1's involvement in autophagy and its potential as a therapeutic target in ciliopathy-related conditions. Its recombinant form provides a standardized tool to dissect centrosome-related pathways and validate genetic mutations observed in clinical settings.
