Histone deacetylase-2 (HDAC2) is a component of a
complex that mediates transcriptional repression in mammalian cells. A
mouse HDAC2 cDNA was used to identify several recombinant clones
containing the entire mouse HDAC2 gene. The mouse HDAC2 gene spans over
36 kilobase pairs and is composed of 14 exons (ranging from 58 to 362 nucleotides in length) and 13 introns (ranging from 75 base pairs to 19 kilobase pairs in length). Primer extension analysis with total RNA
from NIH3T3 cells revealed a major transcriptional start site at 221 base pairs 5' of the ATG translational start codon. Upstream of the
transcriptional start site, no canonical TATA box was found, but
binding sites for several known transcription factors were identified.
Transient transfection studies with 5' deletion mutants localized the
promoter to no more than 76 base pairs upstream from the major
transcriptional start site. Fluorescence in situ
hybridization mapped mouse HDAC2 to chromosomal location 10B1, which is
in close proximity to the growth factor-inducible gene
fisp-12. Information concerning the genomic organization and promoter of HDAC2 will be useful in studies of the regulation of
histone deacetylase activities, which in turn are important in studies
of the regulation of transcriptional repression in mammalian cells.
