機能
Control of topological states of DNA by transient breakage and subsequent rejoining of DNA strands. Topoisomerase II makes double-strand breaks. Indirectly ivolved in vitamin D-coupled transcription regulation via its association with the WINAC complex, a chromatin-remodeling complex recruited by vitamin D receptor (VDR), which is required for the ligand-bound VDR-mediated transrepression of the CYP27B1 gene. -
配列類似性
Belongs to the type II topoisomerase family. -
翻訳後修飾
Phosphorylated upon DNA damage, probably by ATM or ATR. -

All lanes : Anti-Topoisomerase II beta/TOP2B antibody (ab125297)
Lane 1 : Wild-type HEK-293T cell lysate
Lane 2 : TOP2B knockout HEK-293T cell lysate
Lysates/proteins at 40 µg per lane.
Performed under reducing conditions.
Predicted band size: 183 kDa
Observed band size: 183 kDaLanes 1- 2: Merged signal (red and green). Green - ab125297 observed at 183 kDa. Red - Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) observed at 50 kDa.
ab125297 was shown to react with Topoisomerase II beta/TOP2B in wild-type HEK-293T cells in western blot. Loss of signal was observed when knockout cell line ab266340 (knockout cell lysate ab257286) was used. Wild-type HEK-293T and TOP2B knockout HEK-293T cell lysates were subjected to SDS-PAGE. ab125297 and Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) overnight at 4°C at a 1 µg/ml and a 1 in 20000 dilution respectively. 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 in 20000 dilution for 1 hour at room temperature before imaging.

Lane 1: Wild-type NALM-6 cell lysate (20 µg)
Lane 2: Topoisomerase II beta/TOP2B knockout NALM-6 cell lysate (20 µg)
Lane 3: HeLa cell lysate (20 µg)
Lane 4: NIH/3T3 cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab125297 observed at 200 kDa. Red - loading control, ab7291, observed at 50 kDa.
ab125297 was shown to recognize Topoisomerase II beta/TOP2B when Topoisomerase II beta/TOP2B knockout samples were used, along with additional cross-reactive bands. Wild-type and Topoisomerase II beta/TOP2B knockout samples were subjected to SDS-PAGE. ab125297 and ab7291 (loading control to alpha tubulin) were diluted 1 μg/mL and 1/2000 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. -

Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 183 kDa
Observed band size: 183 kDa
Additional bands at: 120 kDa, 150 kDa, 42 kDa, 55 kDa, 66 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 8 minutes
Abcam recommends using milk as the blocking agent - 5%. This blot was produced using a 3-8% Tris Acetate gel under the TA buffer system. The gel was run at 150V for 60 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 5% Milk before being incubated with ab125297 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution.
