The pathway of male sexual development in mammals is initiated by SRY, a gene on the short arm of the Y chromosome. Its expression in the differentiating gonadal ridge directs testicular morphogenesis, characterized by elaboration of Müllerian inhibiting substance (MIS) and testosterone. SRY and MIS each belong to conserved gene families that function in the control of growth and differentiation. Structural and biochemical studies of the DNA binding domain of SRY (the HMG box) revealed a protein-DNA interaction consisting of partial side chain intercalation into a widened minor groove. Functional studies of SRY in a cell line from embryonic gonadal ridge demonstrated activation of a gene-regulatory pathway leading to expression of MIS. SRY molecules containing mutations associated with human sex reversal have altered structural interactions with DNA and failed to induce transcription of MIS.

D009095 Mullerian Ducts A pair of ducts near the WOLFFIAN DUCTS in a developing embryo. In the male embryo, they degenerate with the appearance of testicular ANTI-MULLERIAN HORMONE. In the absence of anti-mullerian hormone, mullerian ducts give rise to the female reproductive tract, including the OVIDUCTS; UTERUS; CERVIX; and VAGINA.

D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D004268 DNA-Binding Proteins Proteins which bind to DNA. The family includes proteins which bind to both double- and single-stranded DNA and also includes specific DNA binding proteins in serum which can be used as markers for malignant diseases.
