CC   -!- FUNCTION: Transcriptional regulator that controls a genetic switch in
CC       male development. It is necessary and sufficient for initiating male
CC       sex determination by directing the development of supporting cell
CC       precursors (pre-Sertoli cells) as Sertoli rather than granulosa cells.
CC       Involved in different aspects of gene regulation including promoter
CC       activation or repression. Binds to the DNA consensus sequence 5'-
CC       [AT]AACAA[AT]-3'. SRY HMG box recognizes DNA by partial intercalation
CC       in the minor groove and promotes DNA bending. Also involved in pre-mRNA
CC       splicing (By similarity). In male adult brain involved in the
CC       maintenance of motor functions of dopaminergic neurons (By similarity).
CC       {ECO:0000250|UniProtKB:P36394, ECO:0000250|UniProtKB:Q05066}.
CC   -!- SUBUNIT: Interacts with CALM, EP300, HDAC3, KPNB1, ZNF208 isoform KRAB-
CC       O, PARP1, SLC9A3R2 and WT1. The interaction with EP300 modulates its
CC       DNA-binding activity. The interaction with KPNB1 is sensitive to
CC       dissociation by Ran in the GTP-bound form. Interaction with PARP1
CC       impaired its DNA-binding activity. {ECO:0000250|UniProtKB:Q05066}.
CC   -!- SUBCELLULAR LOCATION: Nucleus speckle {ECO:0000250|UniProtKB:Q05066}.
CC       Cytoplasm {ECO:0000250|UniProtKB:Q05066}. Nucleus
CC       {ECO:0000250|UniProtKB:Q05066}.
CC   -!- PTM: Acetylation of Lys-130 contributes to its nuclear localization and
CC       enhances its interaction with KPNB1. Deacetylated by HDAC3.
CC       {ECO:0000250|UniProtKB:Q05066}.
CC   -!- SIMILARITY: Belongs to the SRY family. {ECO:0000305}.
