QuickView for TOP1;jsessionid=C6500214117C5AE20D078D4E44D41258 (gene)


Gene Symbol:
TOP1 Homo sapiens Homo sapiens
Full name:
DNA topoisomerase I
Synonyms:
TOPI, DNA topoisomerase 1, topoisomerase (DNA) I, type I DNA topoisomerase
Genomic Location:
Chr 20: 39090876-39186541
Description:
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 pseu...
