regulatory proteins

regulatory proteins

1. proteins which regulate the contraction of muscle by controlling the interaction of myosin and actin. Calcium is an essential component of this reaction. The two proteins are troponin and tropomyosin.
2. special proteins that bind to specific regulatory sequences of DNA and act to switch genes on and off and thereby regulate the transcription of genes.
