RelevanceCENPE is a 250-300 kDa human centromere-associated kinesin-like motor protein that accumulates in G2 phase. In contrast to other centromere proteins, CENPE is not detected at centromeres during interphase, and first appears at the centromere region of chromosomes during prometaphase. CENPE function is required for the transition from metaphase to anaphase. CENPE is probably one of the motors responsible for mammalian chromosome movement and/or spindle elongation.
Cellular localizationAssociates with kinetochores during congression, relocates to the spindle midzone at anaphase, and is quantitatively discarded at the end of the cell division.

Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: CENPE knockout HAP1 cell lysate (20 µg)
Lane 3: HeLa cell lysate (20 µg)
Lane 4: HepG2 cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab133583 observed at 310 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab133583 was shown to specifically react with CENPE when CENPE knockout samples were used. Wild-type and CENPE knockout samples were subjected to SDS-PAGE. ab133583 and ab8245 (loading control to GAPDH) were diluted 1/1000 and 1/2000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 h at room temperature before imaging.
ab133583 staining CENPE in the Hela cell line from Human cervix by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with methanol. Samples were incubated with primary antibody (1/500 in PBS) for 1 hour at 22°C. Ab150081 (1/200) was used as the secondary antibody.
