indirect immunofluorescence: 1:100 using HeLa cells microarray: suitable western blot (chemiluminescent): 1:2,000 using whole extract of mouse NIH3T3 and rat PC12 cells western blot (chemiluminescent): 1:5,000 using nuclear extract of human HeLa cells
The gene INCENP (inner centromere protein) encodes an inner centromere protein that forms a component of the chromosomal passenger complex (CPC). It is found to be localized to inner centromeres during mitosis. The CPC also contains Aurora B, survivin, and Borealin.
免疫原
synthetic peptide corresponding to amino acid residues 884-901 of human INCENP with N-terminal added cysteine conjugated to KLH. The corresponding sequence differs by one amino acid in chicken and Xenopuslaevis and by two amino acids in mouse.
應用
Anti-INCENP antibody produced in rabbit has been used in western blotting and immunofluorescence.
生化/生理作用
Studies in knockout mice established INCENP (inner centromere protein) as essential for mouse development and viability. Loss of INCENP results in chromosome segregation defects and failures in cytokinesis.
The inner centromere protein encoded by the INCENP gene is phosphorylated by Cdk1 (cyclin dependent kinase 1) in mitosis. It is found to be associated with Plk1 (Polo-like kinase) in a polo-box–dependent manner. Plk1 is a serine/threonine kinase that functions in cell cycle, especially in mitosis. INCEP participates in the localization of Bub1 (Budding uninhibited by benzimidazole 1), a serine/threonine kinase involved in spindle checkpoint, to kinetochore. This, in turn, promotes the recruitment of Plk1 to kinetochores. Phosphorylated INCENP stimulates the activity of Aurora B kinase at centromeres and the central spindle that is important for chromosome segregation and cytokinesis, respectively.

Sister centromere fusion is a process unique to meiosis that promotes co-orientation of the sister kinetochores, ensuring they attach to microtubules from the same pole during metaphase I. We have found that the kinetochore protein SPC105R/KNL1 and Protein Phosphatase 1

The function of the Aurora B kinase at centromeres and the central spindle is crucial for chromosome segregation and cytokinesis, respectively. Herein, we have investigated the regulation of human Aurora B by its complex partners inner centromere protein (INCENP) and

Polo-like kinase 1 (Plk1) is required for the generation of the tension-sensing 3F3/2 kinetochore epitope and facilitates kinetochore localization of Mad2 and other spindle checkpoint proteins. Here, we investigate the mechanism by which Plk1 itself is recruited to kinetochores. We

Haspin phosphorylates histone H3 at threonine-3 (H3T3ph), providing a docking site for the Aurora B complex at centromeres. Aurora B functions to correct improper kinetochore-microtubule attachments and alert the spindle checkpoint to the presence of misaligned chromosomes. We show that
