Question

What role does a transcription factor play in a signal transduction pathway?

Answer 1

Answer:

The answer is (1) It initiates a cascade.

Explanation:

Signal transduction pathways regulate many important cellular functions such as growth, differentiation, metabolism, and survival. Many of these signaling pathways are altered in human cancer.

Receptor tyrosine kinases are cell surface receptors that play a role in the signaling pathways governing cellular processes of metabolism, intercellular communications, differentiation, survival, and proliferation.

They bind to their corresponding growth factors, triggering the downstream signaling cascade.
