This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Pharmacodynamics, Subject name: Pharmacology
Atrial Natriuretic Peptide receptors belong to which of the following type of receptors: 
Select and explain. 
A. G-protein coupled receptors, B. Ligand-gated guanylyl cyclase receptor, C. Tyrosine kinase receptors, D. JAK-STAT receptors
B: Ligand-gated guanylyl cyclase receptor
Answer: B: Ligand-gated guanylyl cyclase receptor 
Explanation: Natriuretic peptides Natriuretic peptide receptors are Transmembrane ligand-gated guanylyl cyclase receptors. ANP and BNP are selective agonist for A-type natriuretic receptor (NPR-A). CNP is selective agonist for B-type natriuretic receptor (NPR-B). The NPR-C has an extracellular domain similar to those of NPR-A and NPR-B but does not contain the guanylyl cyclase domain.
