General annotation (Comments)

Function	Transcriptional regulator which control 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. In male adult brain involved in the maintenance of motor functions of dopaminergic neurons By similarity. Involved in different aspects of gene regulation including promoter activation or repression. SRY HMG box recognizes DNA by partial intercalation in the minor groove. Facilitates DNA bending. Also involved in pre-mRNA splicing By similarity. Binds to the DNA consensus sequence 5'-[AT]AACAA[AT]-3'. Ref.12
Subunit structure	Interacts with KPNB1, ZNF208 isoform KRAB-O, PARP1 and SLC9A3R2. The interaction with KPNB1 is sensitive to dissociation by Ran in the GTP-bound form. Interaction with PARP1 impaired its DNA-binding activity. Interacts with CALM, EP300, HDAC3 and WT1 By similarity. The interaction with EP300 modulates its DNA-binding activity By similarity. Ref.11 Ref.14 Ref.15 Ref.17
Subcellular location	Nucleus speckle By similarity. Cytoplasm. Note: Colocalizes in the nucleus with ZNF208 isoform KRAB-O and tyrosine hydroxylase (TH). Colocalizes with SOX6 in speckles By similarity. Colocalizes with CAML in the nucleus By similarity. Ref.11 Ref.14 Ref.16
Tissue specificity	Expressed in the substantia nigra of the brain (at protein level). Expressed in diencephalon, cortex, the substantia nigra of the midbrain and the medial mammillary bodies of the hypothalamus of male, but not female. Ref.14 Ref.16 Ref.9
Developmental stage	Expressed in gonadal somatic pre-Sertoli cells from 10.5 to 11.5 dpc. Expressed in pre-Sertoli cells located centrally in the genital ridge and then later in cells located at the cranial and caudal poles (at protein level). Ref.17 Ref.7 Ref.8 Ref.10
Post-translational modification	Phosphorylated on serine residues by PKA By similarity. Phosphorylation by PKA enhances its DNA-binding activity and stimulates transcription repression By similarity. Acetylation of Lys-81 contributes to its nuclear localization and enhances its interaction with KPNB1. Deacetylated by HDAC3 By similarity. Poly-ADP-ribosylated by PARP1 By similarity. ADP-ribosylation reduces its DNA-binding activity By similarity.
Polymorphism	Different alleles occur in strains of Mus musculus (molossinus or domesticus). In particular the poly-Gln region in 167-177 is polymorphic with either 11, 12 or 13 Gln. The nature of this poly-Gln tract could affect the protein's function by disturbing its secondary structure, perhaps by preventing efficient contact with another protein.
Miscellaneous	DNA binding and bending properties of the HMG domains of mouse and human SRY differ form each other. Mouse SRY shows less extensive minor groove contacts with DNA and a higher specificity of sequence recognition than human SRY.
Sequence similarities	Belongs to the SRY family. Contains 1 HMG box DNA-binding domain.
