G protein-coupled receptors as candidates for modulation and activation of the chemical senses in decapod crustaceans.

ABSTRACT: Many studies have characterized class A GPCRs in crustaceans; however, their expression in crustacean chemosensory organs has yet to be detailed. Class A GPCRs comprise several subclasses mediating diverse functions. In this study, using sequence homology, we classified all putative class A GPCRs in two chemosensory organs (antennular lateral flagellum [LF] and walking leg dactyls) and brain of four species of decapod crustaceans (Caribbean spiny lobster Panulirus argus, American lobster Homarus americanus, red-swamp crayfish Procambarus clarkii, and blue crab Callinectes sapidus). We identified 333 putative class A GPCRs- 83 from P. argus, 81 from H. americanus, 102 from P. clarkii, and 67 from C. sapidus-which belong to five distinct subclasses. The numbers of sequences for each subclass
