Myoactive. CAPA-periviscerokinin 1: Expressed in corpora cardiaca (CC), corpora allata (CA), antennal lobe (AL) and gnathal ganglion (GNG) (at protein level). Expression detected in most animals in CC and CA and in some animals in AL and GNG (at protein level). CAPA-periviscerokinin 2: Expressed in corpora cardiaca (CC), corpora allata (CA), antennal lobe (AL) and gnathal ganglion (GNG) (at protein level). For non-pyroglutamate form, expression in AL detected in all animals, in CC, CA and GNG in most animals (at protein level). For pyroglutamate form, expression in CC and CA detected in most animals, in AL and GNG in some animals (at protein level). CAPA-periviscerokinin 3: Expressed in corpora cardiaca (CC), corpora allata (CA), antennal lobe (AL) and gnathal ganglion (GNG). Expression detected in most animals in CC and CA and in some animals in AL and GNG (at protein level). CAPA-precursor-related peptide 3: Expressed in corpora cardiaca (CC), corpora allata (CA), antennal lobe (AL) and gnathal ganglion (GNG) (at protein level). Expression in CC and CA detected in some animals, expression in Al and GNG detected in few animals (at protein level). CAPA-trypto-pyrokinin: Expressed in corpora cardiaca (CC), corpora allata (CA), antennal lobe (AL) and gnathal ganglion (GNG) (at protein level). Expression in CC, CA and GNG detected in most animals, in AL in some animals (at protein level). Periviscerokinin 1. Periviscerokinin 2. Pyroglutamate-modified periviscerokinin 2. Periviscerokinin 3. CAPA-PP 3. Pyrokinin. Belongs to the pyrokinin family. Further mature peptides might exist.
