TOP3A, TOP3, DNA topoisomerase 3-alpha, DNA topoisomerase III alpha
This gene encodes a DNA topoisomerase, an enzyme that controls and alters the topologic states of DNA during transcription. This enzyme catalyzes the transient breaking and rejoining of a single strand of DNA which allows the strands to pass through one another, thus reducing the number of supercoils and altering the topology of DNA. This enzyme forms a complex with BLM which functions in the regulation of recombination in somatic cells. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2016],catalytic activity:ATP-independent breakage of single-stranded DNA, followed by passage and rejoining.,function:Reduces the number of supercoils in a highly negatively supercoiled DNA. Essential component of the RMI complex, a complex that plays an important role in the processing of homologous recombination intermediates to limit DNA crossover formation in cells.,similarity:Belongs to the prokaryotic type I/III topoisomerase family.,subunit:Directly interacts with BLM and RMI1. Component of the RMI complex, containing at least TOP3A, RMI1 and RMI2. The RMI complex interacts with BLM.,tissue specificity:High expression is found in testis, heart, skeletal muscle and pancreas.,
