Rabbit Polyclonal to Human Alpha1 - Fetoprotein Transcription Factor ( LRH1 / NR5A2 )Alpha1-fetoprotein transcription factor (Ftf), a NR5 fushi tarazu-like receptor, also is known as a€?human B1-binding factora€(tm) (HB1F), 'CYP7A promoter-binding factora€(tm) (CPF), and a€?liver receptor homolog 1a€(tm) (LRH1). Ftf has been shown to affect the transcription of hepatic genes including alpha fetoprotein encoding gene (AFP), viral hepatitis B enhancer II, and 7-alpha-hydroxylase encoding gene (CYP7A1). Ftf has also been shown to affect hepatic cholesterol metabolism and bile acid synthesis. Ftf has been shown to regulate aromatase activities in adipose tissue, and alterations in Ftf expression and/or activity in adipose tissue could have considerable effects on local estrogen production and breast cancer development. LRH has been shown to expressly strongly in gonadal tissues, and may play an important role in the regulation of gonadal function. Three isoforms of Ftf have been identified: wild type (495 aa), CPF variant 1 (contains a 46-aa insertion in the A/B domain), and CPF variant 2 (contains a 172-aa deletion within the D/E domain). Ftf expression has been documented in human adrenal, liver, ovary, testis, and pancreas. ESTs have been isolated from normal human brain, liver/spleen, embryo and uterus tissue libraries. |
