    basic FUNCTION
  • isoform 1 may function as an activator and isoform 2 as a repressor in tissues where both forms are expressed
  • may be involved in epidermal differentiation
  • may function as a transcription factor during development
  • may play important roles in mammalian development
  • an important regulator of the DSG1 genes in the context of hair anchorage and epidermal differentiation
  • transcriptional factor that regulate the expression of the P450 side-chain cleavage enzyme (CYP11A1) in the human placenta (Henderson 2009)
  • cooperative roles of the GRHL genes in epidermal development

  • Grhl1-null mice show an initial delay in coat growth, and older mice exhibit hair loss as a result of poor anchoring of the hair shaft in the follicle
