Transcription factor Sp8 also known as specificity protein 8 (SP-8) or Btd transcription factor (buttonhead)[1] is a protein that in humans is encoded by the SP8 gene.[2][3] Sp8 is a transcription factor in the Sp/KLF family.


Sp8 mediates limb outgrowth during early development.[1] Sp8 deletion in mice resulted in severe exencephaly.[4]
