  • heterodimer of a common alpha chain and a unique beta chain which confers biological specificity to thyrotropin, lutropin, follitropin and gonadotropin
    • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interacting with FOXL2 (novel role for FOXL2 in activin A-regulated FSHB transcription)
  • expression of BRMS1L depends on CTNNB1 activity and contributes to FSHB induction by GNRH1
  • SMAD4 and FOXL2 are essential master regulators of FSHB transcription
  • SMAD4 and FOXL2 are master transcriptional mediators of activin signaling that act together and independently of GNRH to regulate FSHB gene expression and female fertility
  • FOXL2 and SMAD4 play essential roles in human FSHB expression
  • enhancer is directly targeted by activin signaling and activin and GNRH can regulate FSHB transcription
    • cell & other
    REGULATION
    activated by LHX3 LIM homeodomain transcription factor in the pituitary gonadotrope cell
    induced by Activin A, though weak on its own, synergized with GNRH1 to stimulate human FSHB promoter activity
    Other production of gonadotropin FSHB is modulated by positive transcription factors and negative corepressors with different pulse sensitivities
    SMAD4 participates in complexes with SMAD2 and SMAD3 to regulate FSHB expression
    testosterone regulates FSHB transcription, in part, through modulation of various components of the activin-signaling system
