靶點(diǎn)詳情

  • 功能：
    Functions as an androgen transport protein, but may also be involved in receptor mediated processes. Each dimer binds one molecule of steroid. Specific for 5-alpha-dihydrotestosterone, testosterone, and 17-beta-estradiol. Regulates the plasma metabolic clearance rate of steroid hormones by controlling their plasma concentration.
  • 基因功能參考文獻(xiàn)：
    1. SHBG may be of functional importance for rapid effects of olfactory steroids on limbic functions including the control of reproductive behaviours through pheromones PMID: 24681170
    2. Fluorine had no effect on the expression of androgen binding protein and inhibin B mRNA in testis sertoli cells of Sprague Dawley rats. PMID: 21033444
    3. Upstream stimulatory factors (USF1 and USF2) induce Nr5a1 and Shbg gene expression during the onset of rat Sertoli cell differentiation. PMID: 21734262
    4. Data show that the use of alternative SHBG first exons 1A and 1B differentially inhibits translation from the ATG situated in exon 2, which codes for methionine 30 of transcripts that begin with the exon 1 sequence. PMID: 21079794
    5. Results suggest that Sertoli cell-derived androgen-binding protein acts on spermatids by modifying the transition protein-1 mRNA level. PMID: 12573823
    6. A wave of apoptosis during the pre-pubertal period is required for normal spermatogenesis to develop, and our data indicate that this apoptotic wave may be regulated by ABP and/or androgens. PMID: 12831397
    7. ABP was found in neurons of the magnocellular hypothalamic nuclei, the preoptic region and the lateral hypothalamus. ABP varicosities occurred throughout the hypothalamus, the median eminence and the posterior pituitary. PMID: 14625054
    8. ABP expression is regulated in differentiated Sertoli cells by the bHLH and CREB family of transcription factors. PMID: 15112319
    9. Estrogen receptor beta was strongly immunolabeled in pachytene spermatocytes of rat androgen-binding protein transgenic mice and localized in tubular stages in which TUNEL labeling was maximal. PMID: 15215204
    10. There is a significantly higher level of the Shbg transcript in hypodactylous rats compared to SHR controls. PMID: 15222128
    11. Intrahypothalamic expression of ABP may be among the mechanisms necessary for rapid actions of steroids on hypothalamic neuroendocrine systems. PMID: 15927785

  • 亞細(xì)胞定位：
    Secreted. Note=In testis, it is synthesized by the Sertoli cells, secreted into the lumen of the seminiferous tubule and transported to the epididymis.
  • 組織特異性：
    Isoform 2 is only expressed in the liver.
