Transcriptional activator that may play a role in regulating epithelial cell differentiation and proliferation. May act as a repressor for a specific subset of ETS/AP-1-responsive genes, and as a modulator of the nuclear response to mitogen-activated protein kinase signaling cascades. Binds to DNA sequences containing the consensus nucleotide core sequence GGAA. Involved in regulation of TNFRSF10B/DR5 expression through Ets-binding sequences on the TNFRSF10B/DR5 promoter (By similarity). Highly expressed in kidney and lung, weakly in skeletal muscle, heart, and liver, and not detected in brain, spleen or testis. The PNT domain acts as a transcriptional activator. Belongs to the ETS family.
