Final answer:
Receptor tyrosine kinase superfamily plays a role in cellular response by initiating downstream signaling pathways. The receptors undergo dimerization and autophosphorylation upon binding of a signaling molecule, triggering a cellular response. These signals are terminated by a phosphatase that removes the phosphates from the receptor.
Step-by-step explanation:
Receptor tyrosine kinase superfamily plays a role in cellular response. These receptors are enzyme-linked receptors with a single transmembrane region, and extracellular and intracellular domains.
When a signaling molecule binds to the extracellular domain of the receptor, it causes the receptor to dimerize. This leads to auto-phosphorylation of tyrosine residues on the intracellular domain, triggering a downstream cellular response.
The signal is terminated by a phosphatase that removes the phosphates from the phosphotyrosine residues.
