CEP170 Polyclonal Antibody: A Key Tool for Centrosome and Microtubule Research

Posted By: Jackson Roberts

The CEP170 Polyclonal Antibody is a critical reagent for investigating the centrosome protein CEP170, a coiled-coil microtubule-associated protein that plays a significant role in microtubule organization and stability. Its expression and localization make it an essential target for studies involving cell division, mitosis, and centrosomal dynamics.

Overview of CEP170

Key Features of CEP170:

  • Full Name: Centrosomal Protein 170.
  • Localization: Primarily located at the centrosome, particularly at the sub-distal appendages of mature centrioles.
  • Functions:
    1. Anchors microtubules to centrosomes.
    2. Regulates microtubule organization during interphase and mitosis.
    3. Interacts with kinases like Polo-like kinase 1 (Plk1) to facilitate mitotic spindle organization.

CEP170 dysregulation has been linked to various cellular abnormalities and diseases, including cancer, making it a significant target in cancer biology.
