Probable DNA-binding transcriptional activator. Key determinant of the keratinocyte proliferation-differentiation switch involved in appropriate epidermal development (By similarity). Plays a role in regulating mammary epithelial cell proliferation (By similarity). May regulate WDR65 transcription (By similarity).
Subcellular locations: Nucleus, Cytoplasm
Translocates to nucleus in response to an activating signal.
Expressed in normal mammary epithelial cells. Expression is reduced or absent in breast carcinomas.
