CC -!- FUNCTION: Plays a central role in social feeding behavior by
CC synthesizing 3',5'-cyclic guanosine monophosphate (cGMP) from GTP.
CC Oxygen, which probably binds to its heme-binding sites, may regulate
CC social behavior by modulating its activity. cGMP is a common second
CC messenger in sensory transduction and is implicated in oxygen
CC sensation. Indeed, C.elegans exhibits a strong behavioral preference
CC for 5-12% oxygen, avoiding higher and lower oxygen levels; a higher
CC level of oxygen inducing a naturally polymorphic social feeding
CC behavior. Involved in avoidance of hyperoxia and for oxygen-induced
CC aggregation and bordering, probably by mediating oxygen sensing in URX,
CC AQR and PQR sensory neurons. {ECO:0000269|PubMed:15203005}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=GTP = 3',5'-cyclic GMP + diphosphate; Xref=Rhea:RHEA:13665,
CC ChEBI:CHEBI:33019, ChEBI:CHEBI:37565, ChEBI:CHEBI:57746; EC=4.6.1.2;
CC -!- COFACTOR:
CC Name=heme; Xref=ChEBI:CHEBI:30413; Evidence={ECO:0000305};
CC Note=Binds 1 or 2 heme groups per heterodimer. {ECO:0000305};
CC -!- ACTIVITY REGULATION: Regulated by molecular oxygen, which binds to the
CC heme binding site. Probably not activated by nitric oxide (NO) (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: Heterodimer; heterodimerizes with gcy-35, and possibly with
CC other soluble guanylate cyclases.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed in URX, AQR and PQR neurons.
CC {ECO:0000269|PubMed:15220933}.
CC -!- MISCELLANEOUS: There are two types of guanylate cyclases: soluble forms
CC and membrane-associated receptor forms.
CC -!- SIMILARITY: Belongs to the adenylyl cyclase class-4/guanylyl cyclase
CC family. {ECO:0000255|PROSITE-ProRule:PRU00099}.
