Transcriptionally activator that may play a role in regulating the later stages of keratinocytes terminal differentiation (By similarity). Binds to DNA sequences containing the consensus nucleotide core sequence GGA[AT]. Transcriptionally activates the TK promoter. Expressed in lung, kidney, stomach, brain, ovaries, tongue, bladder and mammary glands. In the neonatal stage, and during embryogenesis on days 16, 17 and 19, an expression pattern similar to the adult was observed. In addition at stage 16, expression was detected in small intestine. The PNT domain acts as a transcriptional activator. Belongs to the ETS family.
