Final answer:
False. RPTK signaling does not recruit cytoplasmic PTKs to transduce signals. RPTKs are enzyme-linked receptors that activate target proteins through phosphorylation.
Step-by-step explanation:
False.RPTK signaling does not recruit cytoplasmic PTKs to transduce signals. RPTKs, or receptor tyrosine kinases, are enzyme-linked receptors that play a role in signal transduction. When a signaling molecule binds to the extracellular domain of the RPTK, it causes the receptor to dimerize. Tyrosine residues on the intracellular domain of the receptor are then phosphorylated, triggering a downstream cellular response. This response does not involve the recruitment of cytoplasmic PTKs, but rather the activation of target proteins through phosphorylation.
