Restriction digests of the clone give the following sizes (kb): EcoRI--7.2, 2.6, 1.6; AvaI--3.2, 2.7, 1.9, 1.6, 1.2, 0.7; PstI--5.75, 4.8, 0.85; HindIII--6.8, 4.6; BamHI--7.0, 4.4. The insert contains the following restriction sites (approximate kb from the 5' BamHI site): EcoRI--2.0, 3.6 (exon 2); HindIII--6.6 (exon 7); PstI--4.6, 5.5. Nuclear proteins from tissues expression the gene bind specifically to two regions of intron 3. The sequence of the intron is available in GenBank J04465. A BanII fragment (nt -639 to +1395, or nt 2.0 to nt 4.03 relative to the 5' BamHI site), has been demonstrated to contain sequences recognized by developmentally regulated male transacting factors. Transcriptional control is positive. This fragment has been used to produce transgenic mice which express the gene at high levels in the preputial gland of males and at somewhat lower levels in livers of males. |
