Biological function summary
The p40 protein acts as a transcription factor regulating epithelial stem cell maintenance and differentiation. It is an integral component of the tetrameric complex of the p63 protein family where it influences the transcription of genes involved in cell cycle control and apoptotic pathways. The ΔNp63 variant lacking the N-terminal transactivation domain plays an important role in blocking premature senescence contributing to cell proliferative capacity.
Pathways
P40 is involved in the Notch signaling and the PI3K/AKT signaling pathways. In Notch signaling p40 interacts alongside related proteins like bcl-2 or B28 impacting the regulation of cell fate and differentiation. The PI3K/AKT pathway involves p40 in processes essential for cell survival and proliferation often overlapping with proteins such as AKT and mTOR.
