Overlay histogram showing HeLa cells stained with ab200993 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab200993, 1/50 dilution) for 30 min at 22°C. Isotype control antibody (black line) was rabbit monoclonal IgG [EPR25A] Alexa Fluor® 647 (ab199093) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a solid-state 25mW red diode laser (635 nm) and 675/30 bandpass filter.

补充信息

This supplementary information is collated from multiple sources and compiled automatically.

Topoisomerase II alpha and Topoisomerase II beta also known as TOP2A and TOP2B are enzymes with a vital role in modulating the topological states of DNA. They actively introduce transient double-strand breaks in the DNA helix to manage DNA tangling and supercoiling during replication and transcription. TOP2A has a molecular weight of approximately 170 kilodaltons while TOP2B weighs around 180 kilodaltons. High levels of TOP2A are observed in proliferating cells such as those in the thymus and testis while TOP2B is expressed in nearly all tissues indicating its ubiquitous nature.

Biological function summary

These enzymes participate in fundamental cellular processes including chromosomal segregation replication and transcription. They function in the context of large protein complexes rather than in isolation. TOP2A is often engaged during mitosis due to its cell cycle-dependent expression. In contrast TOP2B's functions spread across various DNA-related actions such as differentiation and development. This distribution emphasizes their respective regulatory roles in both proliferating and resting cells.

Pathways

TOP2A and TOP2B integrate into critical pathways like the DNA replication and repair pathways. As a notable component of these pathways TOP2A interacts closely with proteins like MCM2-7 and ORC complex for replication origin unwinding while TOP2B shares interactions with factors like RNA polymerase II for transcription-related activities. These interactions reflect their involvement in maintaining genomic stability across different cellular conditions.

Aberrations in TOP2A expression or function link closely to numerous cancers reflecting its role in cell proliferation. Furthermore mutations or dysregulation of TOP2B have implications in disorders related to neural development highlighting its role beyond cellular growth control. Other related proteins like BRCA1 also display interactions with TOP2A reinforcing the enzyme's involvement in cancer-related pathways whereas TOP2B’s association with proteins like TAF(II)250 suggests a broader involvement in transcription processes relevant to neural disorders.

靶点信息

Key decatenating enzyme that alters DNA topology by binding to two double-stranded DNA molecules, generating a double-stranded break in one of the strands, passing the intact strand through the broken strand, and religating the broken strand (PubMed : 17567603, PubMed : 18790802, PubMed : 22013166, PubMed : 22323612). May play a role in regulating the period length of BMAL1 transcriptional oscillation (By similarity).
