原阿片皮质素是一种前体蛋白,含有促肾上腺皮质激素、促肾上腺皮质激素、促肾上腺皮质激素和肾上腺素的结构(L-3)。L阐明了牛前阿片皮质素的整个一级结构,揭示了该前激素具有共同的MSH核心的重复结构单元,即四肽His-Phe-Arg-Trp,并且多肽激素是由一对碱性氨基酸残基组成的,在那里进行蛋白质分解[4]。第三个MSH核心,称为r-MSH,位于前体(NPP)的神秘N-末端部分。一般认为,阿片皮质素原在远侧部的促肾上腺皮质激素和中间部的促黑素细胞中合成。现在也有大量证据表明,两个脑叶中前体蛋白的成熟过程是不同的(5,6)。与哺乳动物物种对前阿皮皮质素和相关激素的认识显著发展相比,对低等脊椎动物的这些物质知之甚少。两栖动物青蛙体内类似的前体分子的生物合成已经被证明(‘7-9)。虽然没有直接证据表明鱼类中存在前体蛋白,但已在硬骨鱼(LO-17)和角鱼(18-22)中发现了几种神经中间叶多肽。因此,普通的
Proopiocortin is a precursor protein that contains the structures of ACTH, LPH, MSH, and EP (l-3). l The elucidation of the entire primary structure of bovine proopiocortin revealed that the prohormone has repeating structural units of common MSH core, tetrapeptide His-Phe-Arg-Trp, and that the peptide hormones are divided by pairs of basic amino acid residues where proteolytic processing takes place (4). The third MSH core, termed r-MSH, is located in the cryptic N-terminal portion of the precursor (NPP). It is generally accepted that proopiocortin is synthesized in both the corticotroph of the pars distalis and the melanotroph of the pars intermedia. There is also now substantial evidence that the maturation processes of the precursor protein in the two lobes are different (5, 6).In contrast to the striking development of the knowledge of proopiocortin and the related hormones in mammalian species, only little is known about these substances in the lower vertebrates. The biosynthesis of similar precursor molecules in the frog, an amphibian, has been demonstrated (‘7-9). Although there is no direct evidence for the presence of a precursor protein in fish, several neurointermediate lobe peptides have been identified in chum salmon, a teleost (lo-17), and the dogfish, an elasmobranch (18-22). Therefore, the common
