Transcriptional regulator that controls a genetic switch in male development. It is necessary and sufficient for initiating male sex determination by directing the development of supporting cell precursors (pre-Sertoli cells) as Sertoli rather than granulosa cells. Involved in different aspects of gene regulation including promoter activation or repression. Binds to the DNA consensus sequence 5'-[AT]AACAA[AT]-3'. SRY HMG box recognizes DNA by partial intercalation in the minor groove and promotes DNA bending. Also involved in pre-mRNA splicing (By similarity). In male adult brain involved in the maintenance of motor functions of dopaminergic neurons (By similarity). Interacts with CALM, EP300, HDAC3, KPNB1, ZNF208 isoform KRAB-O, PARP1, SLC9A3R2 and WT1. The interaction with EP300 modulates its DNA-binding activity. The interaction with KPNB1 is sensitive to dissociation by Ran in the GTP-bound form. Interaction with PARP1 impaired its DNA-binding activity. The Gln- and His-rich domain may mediate protein-protein interactions. Acetylation of Lys-81 contributes to its nuclear localization and enhances its interaction with KPNB1. Deacetylated by HDAC3. Belongs to the SRY family.
