The word proctolin first appeared in the literature in 1975 when, in two
landmark papers, the late B. E. Brown and his collaborator A. N. Starratt

reported on the isolation (Brown and Starratt, 1975) and the primary
structure (Starratt and Brown, 1975) of an insect pentapeptide (Arg-TyrLeu-Pro-Thr).
This peptide was named proctolin and was suggested as a
candidate transmitter in insects (Brown, 1975). The history of proctolin’s
identification, however, began almost twenty years ago when B. E. Brown
characterized a myotropic factor in the gut of the cockroach, Periplaneta
arnericana (Brown, 1967). This factor (referred to then as “the gut-factor”)
produced a slow graded contraction of the longitudinal muscles of the
proctodeum (Brown, 1967) and appeared to satisfy some of the criteria
characterizing neuromuscular transmitters.
