We have characterized a precursor protein which gives rise to the neuropeptide Phe-Met-Arg-Phe-amide (FMRFamide) by determining the nucleotide sequence of a genomic and five cDNA clones. The 597-amino-acid protein contains 28 copies of the tetrapeptide FMRFamide, a single Phe-Leu-Arg-Phe-amide (FLRFamide), and other sequences flanked by paired basic residues, some of which have homologies to mammalian brain peptides. The data presented suggest the genes encoding pro-opiomelanocortin, pre-pro-enkephalin, and the hypothalamic releasing factor, cortico-releasing factor (CRF), arose from a common ancestral gene.
通过测定一个基因组克隆和五个cDNA克隆的核苷酸序列,我们鉴定了一种前体蛋白,该蛋白可产生神经肽苯丙氨酸-甲硫氨酸-精氨酸-苯丙氨酸酰胺(FMRF酰胺)。这种含有597个氨基酸的蛋白包含28个四肽FMRF酰胺拷贝、一个苯丙氨酸-亮氨酸-精氨酸-苯丙氨酸酰胺(FLRF酰胺),以及由成对碱性残基侧翼的其他序列,其中一些与哺乳动物脑肽具有同源性。所呈现的数据表明,编码促肾上腺皮质激素原、前脑啡肽原和下丘脑释放因子促肾上腺皮质激素释放因子(CRF)的基因起源于一个共同的祖先基因。
