Tachykinins are active peptides which excite neurons, evoke behavioral responses, are potent vasodilators and secretagogues, and contract (directly or indirectly) many smooth muscles. Associated with sex-specific or age/division of labor-selective behavior and/or physiology of honeybees. Strong expression was detected in the queen and forager heads, while weak and almost no significant expression was detected in the nurse and drone heads, respectively. Incompletely processed peptide. Partial peptide processing. Partial peptide processing. Partial peptide processing. Belongs to the tachykinin family. Intron retention. Intron retention. Intron retention.
