Gene(ID):
CENPF(1063)
Description:
Required for kinetochore function and chromosome segregation in mitosis. Required for kinetochore localization of dynein, LIS1, NDE1 and NDEL1. Regulates recycling of the plasma membrane by acting as a link between recycling vesicles and the microtubule network though its association with STX4 and SNAP25. Acts as a potential inhibitor of pocket protein-mediated cellular processes during development by regulating the activity of RB proteins during cell division and proliferation. May play a regulatory or permissive role in the normal embryonic cardiomyocyte cell cycle and in promoting continued mitosis in transformed, abnormally dividing neonatal cardiomyocytes. Interaction with RB directs embryonic stem cells toward a cardiac lineage. Involved in the regulation of DNA synthesis and hence cell cycle progression, via its C-terminus. Has a potential role regulating skeletal myogenesis and in cell differentiation in embryogenesis. Involved in dendritic cell regulation of T-cell immunity against chlamydia

PTMs:

Hyperphosphorylated during mitosis.

Subcellular Location:

Cytoplasm>Perinuclear region. Nucleus matrix. Chromosome>Centromere>Kinetochore. Cytoplasm>Cytoskeleton>Spindle.
Note: Relocalizes to the kinetochore/centromere (coronal surface of the outer plate) and the spindle during mitosis. Observed in nucleus during interphase but not in the nucleolus. At metaphase becomes localized to areas including kinetochore and mitotic apparatus as well as cytoplasm. By telophase, is concentrated within the intracellular bridge at either side of the mid-body.

Figure 5.| CENPF-mediated transcriptional regulation of CHK1 by ADR.K After transfection with CENPF-siRNA-1 or CENPF-siRNA-2, CHK1 protein was analyzed by western blot. In MCF-7, T47D, MDA-MB-231 and MDA-MB-231/ADR cells, CENPF inhibition caused significant downregulation of CHK1. Additionally, with MDA-MB-231 exposed to ADR, silencing CENPF also led to a reduction in CHK1 protein.
