IXR1

ORD1, L000000881, YKL032C
Transcriptional repressor that regulates hypoxic genes during normoxia; involved in the aerobic repression of genes such as COX5b, TIR1, and HEM13; binds DNA intrastrand cross-links formed by cisplatin; HMG (high mobility group box) domain containing protein which binds and bends cisplatin-modified DNA, blocking excision repair; IXR1 has a paralog, ABF2, that arose from the whole genome duplication

Affinity Capture-MS

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

The HMGB protein Ixr1 interacts with Ssn8 and Tdh3 involved in transcriptional regulation.

Barreiro-Alonso A, Lamas-Maceiras M, Cerdan EM, Vizoso-Vazquez A

Ixr1 is a Saccharomyces cerevisiae transcriptional factor that extensively regulates the response to hypoxia and controls other important cellular functions and DNA repair. During aerobic growth, the Ixr1 repressor function is predominant on regulated promoters of hypoxic genes, although activator effects are also observed on other genes. During hypoxia, Ixr1 expression increases and the number of genes activated by Ixr1 ... [more]

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
