Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IP=Immunoprecipitation,

Specificity / Sensitivity

CEP55 (D1L4H) Rabbit mAb recognizes endogenous levels of total CEP55 protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val459 of human CEP55 protein.

Western Blotting

Western Blotting

Western blot analysis of extracts from MCF7 cells, untreated (-) or treated with Doxorubicin #5927 (0.5 μM, 24 hr; +) or UV (100 mJ, 6 hr recovery; +), using CEP55 (D1L4H) Rabbit mAb (upper) and β-Actin (D6A8) Rabbit mAb #8457 (lower).



Immunoprecipitation of CEP55 from MCF7 cell extracts. Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is CEP55 (D1L4H) Rabbit mAb. Western blot was performed using CEP55 (D1L4H) Rabbit mAb. A light chain-specific secondary antibody was used.

The 55 kDa centrosomal protein (CEP55) is a widely expressed centrosome and midbody-associated protein that regulates cytokinesis, including completion of the final step during cytokinesis known as abscission (1,2). CEP55 activity during abscission is negatively regulated by p53 through Polo-like kinase 1 (3,4). The breast and ovarian cancer DNA repair protein BRCA2 interacts with CEP55 and plays a regulatory role during abscission (5). Research studies demonstrate that CEP55 is also involved in the regulation of Akt signaling, autophagy, and may be a biomarker in human cancer (reviewed in 6). The correlated overexpression of CEP55, the transcription factor FoxM1, and the HELLS helicase is seen in head and neck squamous cell carcinoma (7,8). Additional studies demonstrate that CEP55 expression regulates cell proliferation in gastric carcinoma (9).
