The complete organization of the human progesterone receptor (hPR) gen
e has been determined. It spans over 90 kbp and contains eight exons.
The first exon encodes the N-terminal part of the receptor. The DNA bi
nding domain is encoded by two exons, each exon corresponding to one z
inc finger. The steroid binding domain is encoded by five exons. The n
ucleotide sequence of 1144 bp of the 5' flanking region has been deter
mined.
