    protein that helps activate gene expression by binding to transcription factors

    A transcription co-activator is a protein that helps turn on the expression of specific genes by binding to transcription factors, which are proteins that directly interact with DNA. While co-activators do not bind to DNA themselves, they facilitate the assembly of the transcription machinery, enhancing the efficiency of gene transcription. This process is crucial for regulating various biological functions, including hair growth and the response to conditions like alopecia.
