Protein Array - Anti-Topoisomerase II alpha antibody [TOP2A/1362] (AB219321)
ab219321 was tested in protein array against over 19000 different full-length human proteins.
Z- and S- Score : The Z-score represents the strength of a signal that a monoclonal antibody (MAb) (in combination with a fluorescently-tagged anti-IgG secondary antibody) produces when binding to a particular protein on the HuProtTM array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If targets on HuProtTM are arranged in descending order of the Z-score the S-score is the difference (also in units of SD's) between the Z-score. S-score therefore represents the relative target specificity of a MAb to its intended target.
A MAb is specific to its intended target if the MAb has an S-score of at least 2.5. For example if a MAb binds to protein X with a Z-score of 43 and to protein Y with a Z-score of 14 then the S-score for the binding of that MAb to protein X is equal to 29.

Biological function summary
TOP2A is essential for chromosome condensation segregation and relief of DNA torsional stress during mitosis. It does not function in isolation but interacts with other proteins as part of the larger DNA topoisomerase complex. This complex maintains DNA integrity during cellular processes such as transcription and replication. TOP2A's activity ensures that cells can duplicate their genetic material accurately facilitating proper cell division and maintaining genomic stability.
Pathways
TOP2A plays a significant role in the DNA replication and cell cycle regulation pathways. It interacts closely with proteins like CDC2 (cyclin-dependent kinase 1) and is regulated by cyclins which control the timing of cell cycle progression. Additionally TOP2A is involved in the DNA damage response pathway where it collaborates with proteins such as ATM (ataxia-telangiectasia mutated) emphasizing its importance in maintaining DNA structure during replication stress.
