Target
-
RelevanceCDCA2 is a regulator of chromosome structure during mitosis. It is required for condensin-depleted chromosomes to retain their compact architecture through anaphase. It acts by mediating the recruitment of phosphatase PP1-gamma subunit (PPP1CC) to chromatin at anaphase and into the following interphase. At anaphase onset, its association with chromatin targets a pool of PPP1CC to dephosphorylate substrates. CDCA2 is essential for cell viability.
-
Cellular localizationNuclear. Excluded from the nucleolus. Present in nucleoplasm throughout the G1, S and G2 stages of the cell cycle. During M phase, it becomes diffuse throughout the cell as the nuclear membrane breaks down, and faintly accumulates later on metaphase chromatin. As the cell progresses to anaphase, it accumulates on chromatin.

Predicted band size: 113 kDa
Observed band size: 125 kDa why is the actual band size different from the predicted?
Additional bands at: 40 kDa. We are unsure as to the identity of these extra bands. -
Immunocytochemistry/ Immunofluorescence - Anti-CDCA2 antibody (ab45129)ICC/IF image of ab45129 stained HepG2 cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab45129, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899 Dylight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
