IXR1/YKL032C Summary Help

Standard Name IXR1 1 (see Nomenclature conflict Note)
Systematic Name YKL032C
Alias ORD1 2
Feature Type ORF, Verified
Description Protein that binds DNA intrastrand cross-links formed by cisplatin; contains two HMG (high mobility group box) domains, which confer the ability to bend cisplatin-modified DNA; mediates aerobic transcriptional repression of COX5b; IXR1 has a paralog, ABF2, that arose from the whole genome duplication (1, 2, 3, 4)
Name Description Intrastrand cross (X)-link Recognition 1
