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}.
