Relevance
CDCA2 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 localization
Nuclear. 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.
