| 6. | The cdna contains 947 nucleotides that codes for a precursor protein of 216 amino acids . sequence analysis shows that the n - terminal 1 - 25 amino acid sequence is a predicted signal peptide and other 26 - 216 amino acid sequence is a mature peptide which has no transmembrane domain
Ecbp21cdna全长947bp ，编码216个氨基酸，序列分析显示其n端1 - 25氨基酸为信号肽， 26 - 216氨基酸为成熟蛋白肽段，并且不具有跨膜结构域。 |
| 7. | This peptide is derived from proteolytic processing of the amyloid precursor protein ( app ) . an increasing ' amount of experiments show that a p can induce various toxic reaction in brain , thus play a causal role in the pathogenesis of alzheimer ' s disease ( ad ) . in the meantime , the incapability of neurons to regenerate in ad patients means that it may inhibit the proliferation , differentiation and even survival of nscs
