    at STAGE
  • a PKA site N-terminal to the HMG box , and two nuclear localization signals (NLSs) that flank the DNA binding high mobility group (HMG) domain, the beta-NLS and the CALM1-NLS
  • a central HMG DNA-binding domain
  • a conserved motif of DNA binding (sharp binding is required for transcriptional activation and testis determination), a DNA-binding domain characteristic of some high mobility group proteins (HMG box)
  • a glutamine repeat
    interspecies homolog to murine Sry
  • SRY family
  • CATEGORY regulatory , transcription factor
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,nucleus,nucleoplasm,nuclear bodies,nuclear speckles
  • nucleocytoplasmic shuttling of SRY is necessary for robust initiation of testicular development
  • detected in the human male, but not female substantia nigra pars compacta
  • SRY, RPS7 and RPL13A were co-localized in nuclear speckles
  • basic FUNCTION
  • modulator of LINE retroposons promoter activity, regulator of a genetic switch in male development
  • required for testicular differentiation through the nuclear localization signal
  • activates both MAOA-promoter and catalytic activities (Wu 2009)
  • responsible for initiating male sexual differentiation
  • may function by repressing the ovarian determinant gene, RSPO1, action in the ovarian developmental pathway and activates genes, such as SOX9, important for testis differentiation at the onset of gonadogenesis (Peng 2009)
  • transcriptional activator of mammalian testis determination, but this SRY action is limited to a certain time period during embryogenesis (
  • plays an important role in activities associated with nuclear speckles
  • in conjunction with SRY, WDR5 plays an important role in sex determination
  • plays a role as a positive regulator of catecholamine synthesis and metabolism in the human male midbrain
  • nucleocytoplasmic shuttling of SRY is necessary for robust initiation of testicular development (PMId: 24003159)
  • CELLULAR PROCESS nucleotide, transcription
    PHYSIOLOGICAL PROCESS reproduction/sex
    a component
  • component of TDF
  • SRY, ZNF208/KRAB, and TRIM28 proteins formed a stable ternary protein complex (Peng 2009)
    DNA binding
    small molecule
  • interacting with CITED2 (CITED2 acts in the gonad with WT1 and NR5A1 to increase the expression of SRY levels to attain a critical threshold to efficiently initiate testis development) (Buaas 2009)
  • interactions with other co-regulators, particularly ZNF208, are essential for its functions as either a transactivator or repressor of its target genes (Peng 2009)
  • recruits the KRAB-TRIM28 complex as a chromatin modulator (Peng 2009)
  • binds directly to a testis-specific enhancer of SOX9 (TES) and activates SOX9 expression in co-operation with steroidogenic factor 1 (SF1)
  • TFCP2 is an essential transcription factor for SRY expression regulation
  • RPS7 (ribosomal protein S7) and RPL13a (ribosomal protein L13a) interact with the HMG (high-mobility group) box domain of SRY
  • SRY and NR5A1 co-operate to activate the human SOX9 homologous TES, a process dependent on phosphorylated NR5A1
  • SRY acts directly on the TCF21 promoter to in part initiate a cascade of events associated with Sertoli cell differentiation and embryonic testis development
  • WDR5, which encodes a WD-40 repeat protein, is a direct target of SRY (interaction of WDR5 with SRY resulted in activation of SOX9 while repressing the expression of CTNNB1)
  • HSPA8 plays a key role in CALM1-dependent nuclear import of SRY
  • SRY upregulation after dopamine cell injury is initially a protective response in males, but diminishes with gradual loss in dopamine cells, and dysregulation of SRY may potentially contribute the susceptibility of males to Parkinson disease
  • transcriptional factor SRY specifically binds to different sites in the promoter sequence and has the ability to control CATSPER1 gene transcription
