Protein attributes

Sequence length	289 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Tachykinins are active peptides which excite neurons, evoke behavioral responses, are potent vasodilators and secretagogues, and contract (directly or indirectly) many smooth muscles. Stimulates gut muscle contractions. Ref.1
Subcellular location	Secreted Potential.
Tissue specificity	Strong expression is seen in a group of 14 cells plus one isolated cell in the midgut of stage 17 embryos. Also expressed in a pair of medially located unidentified cells, just posterior to the brain, and in two lateral groups of cells that may be associated with tracheae. Expression in the larval gut is restricted to cells with endocrine cell-like morphology in the posterior midgut, just anterior to the malphigian tubules. In the brain, expression is detected in a restricted number of neuronal cell bodies. Expression in the adult female gut is restricted to the midgut with no expression detected in the hindgut. Ref.1
Sequence similarities	Belongs to the tachykinin family.
