Transcription factor involved in epidermis differentiation. Required for terminal epidermal differentiation: acts downstream of p63/TP63 and activates expression of late epidermal differentiation genes. Specifically binds to the promoter of KLF4 and promotes its expression.
Subcellular locations: Nucleus
Expressed in the skin, prostate, lung, placenta and thymus, and at low level in T-cells. Not expressed in peripheral blood leukocytes, pancreas and brain. Clearly expressed in primary keratinocytes but not in fibroblasts.
