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. Acetylation contributes to its nuclear localization and deacetylation by HDAC3 induces a cytoplasmic delocalization (By similarity). Colocalizes in the nucleus with ZNF208 isoform KRAB-O and tyrosine hydroxylase (TH) (By similarity). Colocalizes with SOX6 in speckles. Colocalizes with CAML in the nucleus (By similarity). Expressed in the genital ridge. Expressed in male pig embryo between E21 and E26. Not detected in E31 embryos. Belongs to the SRY family. The tenuous nature of sex - Issue 80 of March 2007
