family, involved in solid tumor acidification. This enzyme is a marker of tumor hypoxia and a
prognostic factor for several human cancers. In a recent paper, we showed that CA IX
interacts with cullin-associated NEDD8-dissociated protein 1 (CAND1), a nuclear protein
involved in gene transcription and assembly of SCF ubiquitin ligase complexes. A functional
role for this interaction was also identified, since lower CA IX levels were observed in cells …
