TOXIN INTERACTIONS WITH TRPV1

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 用于分析离子通道结构/功能的最有力的工具之一是鉴定天然毒素激动剂和拮抗剂。 几种生物产生作用于离子通道的小蛋白质毒素，帮助捕获或防御猎物。 我们建议研究毒素与离子通道TRPV 1的相互作用。 我们将使用MALDI质谱法来评估通过反相色谱分离的毒素的分子组成。 UCSF质谱设施将协助收集，以确定分离毒素的分子量。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. One of the most powerful tools for analyzing ion channel structure/function has been the identification of natural toxins agonists and antagonists. Several organisms produce small protein toxins that act on ion channels and aid in prey capture or defense. We propose to study toxin interaction with the ion channel TRPV1. We will use MALDI mass spectrometry to assess the molecular composition of toxins isolated by reverse phase chromatography. The UCSF Mass Spectrometry Facility will assist in the collection to determine the molecular weight of isolated toxins.
