ANPB a transmembrane guanylyl cyclase enzyme with a tyrosine kinse domain. Receptor for natriuretic peptide receptor B, one of two integral membrane receptors for natriuretic peptides. Contains five functional domains: an extracellular ligand-binding domain, a single membrane-spanning region, and intracellularly a protein kinase homology domain, a helical hinge region involved in oligomerization, and a carboxyl-terminal guanylyl cyclase catalytic domain. Is the primary receptor for C-type natriuretic peptide (CNP), which upon ligand binding exhibits greatly increased guanylyl cyclase activity. Multiple mutations linked to acromesomelic dysplasia (skeletal malformation). 3 isoforms of the human protein are produced by alternative splicing.
