A myotropic peptide, termed Lom-AG-myotropin, was isolated from extracts of 4400 accessory gland complexes of males of the locust, Locusta migratoria; the following sequence was derived: Gly-Phe-Lys-Asn-Val-Ala-Leu-Ser-Thr-Ala-Arg-Gly-Phe-NH2. This sequence is completely different from all presently known myotropic peptides from Locusta or other insects. The Lom-AG-myotropin is active on the oviduct and hindgut of Locusta migratoria and Leucophaea maderae. The stimulatory activity is, in both insects, 1000 times greater on the oviduct than on the hindgut, suggesting a specificity for the oviduct.
一种亲肌肽，命名为Lom-AG-促肌动蛋白，是从4400个飞蝗（Locusta migratoria）雄性附腺复合体的提取物中分离出来的；推导得到以下序列：甘氨酸-苯丙氨酸-赖氨酸-天冬酰胺-缬氨酸-丙氨酸-亮氨酸-丝氨酸-苏氨酸-丙氨酸-精氨酸-甘氨酸-苯丙氨酸-NH2。该序列与目前已知的来自飞蝗或其他昆虫的所有亲肌肽完全不同。Lom-AG-促肌动蛋白对飞蝗和马德拉蜚蠊（Leucophaea maderae）的输卵管和后肠有活性。在这两种昆虫中，其刺激活性在输卵管上比在后肠上高1000倍，表明对输卵管具有特异性。
