  • Function
    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 (By similarity). 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 (By similarity). Promotes DNA bending. SRY HMG box recognizes DNA by partial intercalation in the minor groove. Also involved in pre-mRNA splicing. Binds to the DNA consensus sequence 5'-[AT]AACAA[AT]-3'.
  • Involvement in disease
    Defects in SRY are a cause of gonadal dysgenesis XY female type (GDXY) [MIM:400044]; also known as complete SRY-related 46,XY gonadal dysgenesis or 'XY females' or Swyer syndrome. Patients are found to have a 46,XY karyotype. They suffer rapid and early degeneration of their gonads, which are present in the adult as 'streak gonads', consisting mainly of fibrous tissue and variable amounts of ovarian stroma. As a result these patients do not develop secondary sexual characteristics at puberty. The external genitalia in these subjects are completely female, and Muellerian structures are normal. In contrast, subjects with 46,XY partial gonadal dysgenesis have ambiguous genitalia, a mix of Muellerian and Wolffian structures, and dysgenic gonads.
    Note=A 45,X chromosomal aberration involving SRY is found in Turner syndrome, a disease characterized by gonadal dysgenesis with short stature, "streak gonads", variable abnormalities such as webbing of the neck, cubitus valgus, cardiac defects, low posterior hair line. The phenotype is female.
    Defects in SRY are a cause of true hermaphroditism (TRUHER) [MIM:400045]; also known as complete SRY-positive 46,XX gonadal dysgenesis. A true hermaphrodite must have both mature ovarian and mature testicular tissue with histologic evidence of follicles and tubules, respectively. It is a genetically heterogeneous condition. The genotype of most affected individuals is 46,XX, but many have 46,XY or a mosaic of 46,XX/46,XY. True hermaphroditism can be caused also by chromosomal translocation.
  • Sequence similarities
    Belongs to the SRY family.
    Contains 1 HMG box DNA-binding domain.
  • Domain
    DNA binding and bending properties of the HMG domains of human and mouse SRY differ form each other. Human SRY shows more extensive minor groove contacts with DNA and a lower specificity of sequence recognition than mouse SRY.
  • Post-translational
    Phosphorylated on serine residues by PKA. Phosphorylation by PKA enhances its DNA-binding activity and stimulates transcription repression. Acetylation of Lys-136 contributes to its nuclear localization and enhances its interaction with KPNB1. Deacetylated by HDAC3. Poly-ADP-ribosylated by PARP1. ADP-ribosylation reduces its DNA-binding activity.
  • Cellular localization
    Nucleus speckle. Cytoplasm. Colocalizes with SOX6 in speckles. Colocalizes with CAML in the nucleus. Colocalizes in the nucleus with ZNF208 isoform KRAB-O and tyrosine hydroxylase (TH).

Sex-determining region Y protein (Testis-determining factor) Rattus norvegicus (Rat) shows a homology of 86.0% to the immunogen of ab22166 and we would expect a cross reaction of the antibody.

Please also be aware the HMG box transcription fa...

Thank you for your reply.

I apologize for any confusion. We do not carry embryonic mouse testis lysates. I can confirm that the WB image is from fetal mouse, so I will update the image caption to avoid further confusion.

Thank you for your inquiry.

We do sell the positive control mouse testis whole cell lysate as ab29289, but this is something that you would have to purchase.

Thank you for your reply.

Mice were immunized with a full length SRY protein and then monoclonal antibodies were derived from that. It is not uncommon to not map the specific sequence of amino acids that is targeted by the monoclonal an...

Thank you for contacting Abcam regarding ab22166.

The immunogen is the full length protein fused with a proprietary tag. The specific epitope has not been mapped so we do not know where the antibody specifically binds to the protein. Read More

Thank you very much for your interest in ab22166.  This should be a male sex-specific protein. http://www.uniprot.org/uniprot/Q05738 To our knowledge, ab22166 has not been tested in flow cytometry (FC). Therefore, I can offer a discount off a f...
