克隆了大鼠B神经生长因子(NGF)基因组序列,并测定了其核苷酸序列。大鼠神经生长因子与其他已知的神经生长因子在前原肽和3′端非翻译区具有很高的同源性。推测的信号序列、对三级结构重要的半胱氨酸残基、可能的糖基化位点和蛋白水解裂解为成熟NGF所需的二元氨基酸在物种间是保守的。疏水性图和氨基酸序列的比较揭示了在NGF的外表面上的进化趋异结构域,这可能是各种NGF的免疫交叉反应性差的原因。用大鼠特异性寡脱氧核苷酸原位杂交表明,海马颗粒和锥体细胞层中均有高水平的NGF mRNA合成。这些结果是一致的一个作用,神经生长因子在中枢神经系统作为一个神经元释放,基底前脑胆碱能神经元逆行运输的神经营养因子。
A rat b̃‐nerve growth factor (NGF) genomic sequence encoding the entire 3′ exon of preproNGF was cloned, and its nucleotide sequence was determined. Rat NGF shows very high homology with other known NGFs in both the prepropeptide and the 3′ untranslated regions. The presumptive signal sequence, the cysteine residues important for tertiary structure, possible glycosylation sites, and dibasic amino acids required for proteolytic cleavage to mature NGF are conserved across species. Comparison of the hydrophobicity plots and amino acid sequences revealed an evolutionary divergent domain on the external surface of NGF, which may account for the poor immunologic crossreactivities of the various NGFs. In situ hydridization with a rat‐specific oligodeoxynucleotide indicated high levels of NGF mRNA synthesis in both hippocampal granule and pyramidal cell layers. These results are consistent with one role for NGF in the CNS as a neuronally released, retrogradely transported neurotrophic factor for basal forebrain cholinergic neurons.
