Rabbit anti-Human TOP2A Polyclonal Antibody

Uniprot Id

P11388

Target Species

Human

Target Name

TOP2A

Target Full Name

DNA topoisomerase 2-alpha

Target Function

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. May play a role in regulating the period length of ARNTL/BMAL1 transcriptional oscillation.

Target Subcellular Location

Cytoplasm. Nucleus, nucleoplasm. Nucleus. Nucleus, nucleolus.

Target Protein Families

Type II topoisomerase family

Target Tissue Specificity

Expressed in the tonsil, spleen, lymph node, thymus, skin, pancreas, testis, colon, kidney, liver, brain and lung. Also found in high-grade lymphomas, squamous cell lung tumors and seminomas.

Target Synonyms

Target Background

This gene encodes a DNA topoisomerase, an enzyme that controls and alters the topologic states of DNA during transcription. This nuclear enzyme is involved in processes such as chromosome condensation, chromatid separation, and the relief of torsional stress that occurs during DNA transcription and replication. It catalyzes the transient breaking and rejoining of two strands of duplex DNA which allows the strands to pass through one another, thus altering the topology of DNA. Two forms of this enzyme exist as likely products of a gene duplication event. The gene encoding this form, alpha, is localized to chromosome 17 and the beta gene is localized to chromosome 3. The gene encoding this enzyme functions as the target for several anticancer agents and a variety of mutations in this gene have been associated with the development of drug resistance. Reduced activity of this enzyme may also play a role in ataxia-telangiectasia.
