Proctolin is an endogenous pentapeptide that acts as an excitatory neuromodulator.
Proctolin can increase the frequency of action potentials, increase the amplitude of muscle contraction, and initiate activity in quiescent systems[1]. In the arthropods, Proctolin acts as a neuromodulator and possibly as a neurohormone. It does not appear to function as a conventional neurotransmitter[2]. Proctolin is a pentapeptide with the mature peptide of RYLPT, and it is the first insect neuropeptide to be sequenced and chemically characterized. The first identification of a Proctolin precursor gene is CG7105 in D. melanogaster. Although a previous study showed that Proctolin is absent in B. mori, this pentapeptide is recently identified in a proteomic analysis of B. mori wings. However, the Bombyx Proctolin gene does not produce a mature peptide because cleavage sites are not present at the N-terminal and C-terminal of the RYLPT sequence, and a similar gene is observed in C. suppressalis. Therefore, a true Proctolin has been considered to be not observed in B. mori and C. suppressalis[3].

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
