Function
- control of topological states of DNA by transient breakage & subsequent rejoining of DNA strands
- topoisomerase 2 makes double-strand breaks
- phosphorylated upon DNA damage, probably by ATM or ATR
- ATP-dependent breakage, passage & rejoining of double-stranded DNA
Structure
- homodimer
- belongs to the type II topoisomerase family
Compartment
Alternative splicing
named isoforms=2
