生长激素释放因子(GRF)被认为介导垂体前叶生长激素(GH)释放和合成的神经和激素控制。它在下丘脑中的存在量很少,多年来阻碍了确定其结构的努力。最近,两个小组独立地鉴定了来自两种人类胰腺肿瘤的具有 GH 释放活性的肽1,2。该肽的抗体已揭示了几种灵长类动物下丘脑中的免疫反应物质3。此外,现在已直接从人类下丘脑4中分离出一种明显相同的肽。通过对 cDNA 表达文库进行寡核苷酸 5-7 和抗体 8-10 筛选,我们在更大的前体蛋白中分离出了编码人胰腺 GRF (hpGRF) 的重组克隆。核苷酸序列预测,GRF 前体的加工应该产生两个功能未知的附加肽。基因组 DNA 的限制性分析表明可能存在单个人类 GRF 基因,并表明胰腺肿瘤和下丘脑蛋白由相同的 mRNA 编码。
Growth hormone-releasing factor (GRF) is believed to mediate both neural and hormonal control of the release and perhaps synthesis of growth hormone (GH) from the anterior pituitary. Its presence in only minute quantities in the hypothalamus hampered for many years efforts to determine its structure. Recently, two groups independently characterized a peptide from two human pancreatic tumours that possessed GH-releasing activity1,2. Antibodies to this peptide have revealed immunoreactive material in the hypothalamus of several primate species3. Furthermore, an apparently identical peptide has now been isolated directly from human hypothalamus4. Using both oligonucleotide5–7 and antibody8–10 screening of a cDNA expression library, we have isolated a recombinant clone encoding human pancreatic GRF (hpGRF) within a larger precursor protein. The nucleotide sequence predicts that processing of GRF from the precursor should generate two additional peptides of unknown function. Restriction analysis of genomic DNA indicates that there is probably a single human GRF gene and suggests that the pancreatic tumour and hypothalamic proteins are encoded by an identical mRNA.
