OrLPT1 ORF encods a polypeptide with 535 amino acid residues (molecular mass of 57.6KDaltons), which shares more than 64% amino acid identity with some other high-affinity Pi transporters of plants. Hydropathy analysis of the deduced polypeptides showed that the OrLPT1 is highly hydrophobic and contains 12 putative membrane-spanning regions.

OrLPT1 ORF 编码长为535 个氨基酸(分子量57.6 KDaltons)的蛋白，与其他植物物种磷酸盐转运蛋白的同源性在64%以上；多肽链的疏水性分析表明，OrLPT1 具有12 个疏水的跨膜区及高亲和力磷酸盐转运蛋白中保守的3 个磷酸化作用位点：蛋白激酶C作用位点、N端糖基化部位和酪蛋白激酶II 作用部位； 3。

The 3D structure of N protein shows that the domain of Ep703 is exposed on the surface of the protein, making the epitope to be readily recognized by antibody. No homology is found between the mimotopes and native epitope. However, they all contain high content of hydrophile amino acids and low content of hydrophobile amino acids.

蛋白的三维结构显示，Ep703的9个氨基酸多肽暴露于蛋白的表面。3个模拟表位与表位Ep703的序列&IQTAFNQGA&相比，相同的氨基酸很少，但是各表位氨基酸的极性却有一个共同的特征：亲水性氨基酸比例较大，疏水性氨基酸比例较少。

The PGFs, for example, basic fibroblast growth factor and transforming growth factor-β〓, mediated the stromal-epithelial interaction through paracrine and autocrine, directly controled the growth, differentiation and apoptosis of prostatic cells and played an important role during the process of BPH. In the present study, the expression of bFGF and TGFβ〓 in normal and hyperplasic prostate were determined with immunohistochemistry and in situ hybridization.

多肽生长因子，如碱性成纤维细胞生长因子和转化生长因子（TGF-β1）以旁分泌和自分泌的方式介导间质-上皮相互作用，直接调控前列腺细胞的生长、分化和凋亡，在BPH发病过程中发挥着重要作用。

Dendritic cell vaccine was impacted and sensitized by tumor associated antigen and antigen polypeptide in vitro, then was retransfused or immunogenically inoculated to tumour carrier host, can evoked specific CTL's antitumour immunoreaction.

应用肿瘤相关抗原或抗原多肽体外冲击致敏DC制成疫苗，回输或免疫接种于载瘤宿主，可诱发特异性CTL的抗肿瘤免疫反应。

In 1975. This polypeptide has been identified as one of such factors that has more bioactivities. The beneficial effects of TNF usually predominate with low level which produced host defence immunologically.

随着研究的不断深入，对其本质有了充分的认识：该多肽细胞因子具有广泛的生物学活性，低水平时，参与机体的免疫防御；高水平时，会给机体造成严重损害。
