Protein

Cardio acceleratory peptide 2b

Gene

capa

Organism
Drosophila pseudoobscura pseudoobscura (Fruit fly)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

CAP-1 and CAP-2, but not CAP-3 are ligands for the Capa receptor. CAP-1 and CAP-2 are probably components of the signal transduction pathway that leads to Malpighian tubule fluid secretion via the second messenger nitric oxide (By similarity).By similarity
