RT   "Sequence of guinea pig guanylin and guanylyl cyclase C (GC-C) cDNA:
RT   expression and tissue distribution.";
RL   Submitted (AUG-1996) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Endogenous activator of intestinal guanylate cyclase. It
CC       stimulates this enzyme through the same receptor binding region as the
CC       heat-stable enterotoxins.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- SIMILARITY: Belongs to the guanylin family. {ECO:0000305}.
