TOP1 - DNA topoisomerase I Gene
Also Known as TOPI
Species: Homo sapiens
About TOP1
This gene has 6 transcripts (splice variants), 273 orthologues, 1 paralogue and is associated with 81 phenotypes. Ubiquitous expression in bone marrow (RPKM 33.0), lymph node (RPKM 31.6) and 25 other tissues.
Summary
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 altering the topology of DNA. This gene is localized to chromosome 20 and has pseudogenes which reside on chromosomes 1 and 22. [provided by RefSeq, Jul 2008]
