Structure and function studies of the human voltage-gated proton channel HV1

电压门控质子通道 Hv1 在生理学中具有许多意义。迄今为止最好理解的是吞噬作用中氧化爆发期间的电荷补偿。最近的出版物发现 Hv1 在转移性乳腺癌、结肠癌和直肠癌细胞、精子、B 细胞、小胶质细胞和嗜碱性细胞中具有额外的生理重要性。这些意义使 Hv1 成为一个有前途的靶标，用于设计抗癌症、不孕不育、中风和免疫功能障碍的药物。我们将研究 Hv1 的结构和功能。因此，我们将使用膜片钳技术结合分子动力学模拟来生成和完善hHv1的同源模型。该计算机模型将成为加强Hv1合理药物设计的基础。此外，我们能够直接在表达系统和天然细胞上测试新药的效率。

The voltage-gated proton channel Hv1 has many implications in physiology. The by far best understood is the charge compensation during the oxidative burst in phagocytosis. Recent publications found additional physiological importance of Hv1 in metastasized breast, colon and rectal cancer cells, sperm, B-cells, microglia, and Basophiles. These implications turn Hv1 into a promising target, to design drugs against cancer, infertility, stroke and immune malfunction.We will investigate the structure and function of Hv1. Therefore we will use the patch clamp technique combined with molecular dynamics simulations to generate and refine a homology model of hHv1. The computer model will be the basis to enhance rational drug design of Hv1. Furthermore we are able to test the efficiency of new drugs directly on expression systems and native cells.
