Summary
Description
A hormone that controls sex pheromone production in females and pheromone responsiveness in male. Also mediates visceral muscle contractile activity (myotropic activity). Identical to MRCH which is implicated in the formation of both melanin in the cuticle and ommochrome in the epidermis of armyworm species.
Diapause hormone (DH) is responsible for induction of embryonic diapause.
The three SGNPS are far less active than DH in inducing diapause eggs. Beta-SGNP expressed higher pban activity than PBAN-I, but alpha- and gamma-SGNP were far less active in pheromonotropic activity.

A hormone that controls sex pheromone production in females and pheromone responsiveness in male. Also mediates visceral muscle contractile activity (myotropic activity).
Pheromone biosynthesis-activating neuropeptide: A hormone that controls sex pheromone production in female moths and pheromone responsiveness in male (PubMed:9753769).
A hormone that controls sex pheromone production in females and pheromone responsiveness in male. Also mediates visceral muscle contractile activity (myotropic activity) (By similarity).
Pyrokinins mediate visceral muscle contractile activity (myotropic activity).
Miscellaneous
Juvenile hormone seems to allow PBAN release, which then induces pheromone biosynthesis.
PBAN is produced independent of the photoperiod. The circadian rhythm in pheromone production is due to the circadian rhythm of PBAN release.
The structural similarity of PK1 and PK2 to CAPA-PK might compensate for the apparent absence of CAPA-PK in ants.
Similarity
Belongs to the pyrokinin family.
