The SIN3A-HDAC (histone deacetylase) complex is a master transcriptional
repressor, required for development but often deregulated in disease. Here, we
report that the recently identified new component of this complex, SINHCAF (SIN3A
and HDAC-associated factor)/FAM60A (family of homology 60A), links the SIN3A-HDAC
co-repressor complex function to the hypoxia response. We show that SINHCAF
specifically represses HIF-2? mRNA and protein expression, via its interaction
with the transcription factor SP1 (specificity protein 1) and recruitment of
HDAC1 to the HIF-2? promoter. SINHCAF control over HIF-2? results in functional
cellular changes in in vitro angiogenesis and viability. Our analysis reveals an
unexpected link between SINHCAF and the regulation of the hypoxia response.
