protein regulating gene expression, affecting cell processes and hair growth
c-Jun is a protein that plays a crucial role in regulating gene expression, which means it helps control which genes are turned on or off in a cell. It is part of the AP-1 (activator protein-1) transcription factor complex and is involved in various cellular processes, including cell proliferation, differentiation, and apoptosis. In the context of hair and alopecia, c-Jun can influence hair follicle development and cycling, potentially impacting hair growth and loss.
