CKAP2 (Cytoskeleton-Associated Protein 2), also known as tumor-associated microtubule-associated protein (TMAP), is a mitotic spindle-associated protein involved in cell division and cytoskeletal organization. It plays a critical role in regulating microtubule dynamics during mitosis, particularly in stabilizing spindle poles and ensuring proper chromosome segregation. CKAP2 is predominantly expressed during the G2/M phase of the cell cycle and is downregulated in quiescent cells, highlighting its importance in proliferating cells.
Antibodies targeting CKAP2 are widely used in research to study its expression, localization, and function in cellular processes. Overexpression of CKAP2 has been linked to various cancers, including breast, lung, colorectal, and hepatocellular carcinomas, where it correlates with poor prognosis, tumor aggressiveness, and metastasis. These antibodies enable detection of CKAP2 in techniques like Western blotting, immunohistochemistry (IHC), and immunofluorescence (IF), aiding investigations into its role in cancer progression and mitotic regulation. Additionally, CKAP2 antibodies help explore its interaction with other mitotic regulators, such as Aurora kinases, and its potential as a therapeutic target. Recent studies also suggest CKAP2’s involvement in chromosomal instability, making it a biomarker of interest in oncology and cell biology research.
