transcription factor regulating gene expression and cellular processes
Activator Protein 1 (AP-1) is a transcription factor, which means it helps control the expression of certain genes. It is a complex of proteins that binds to specific DNA sequences, thereby regulating processes like cell growth, differentiation, and apoptosis. In the context of hair biology, AP-1 can influence the growth cycle of hair follicles and may play a role in conditions like alopecia.
