项目摘要
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.

表示该子项目使用的中心基础设施的估计数量,
不是由NCRR赠款提供给次级项目或次级项目工作人员的直接资金。
分析离子通道结构/功能的最有力工具之一是鉴定天然毒素、激动剂和拮抗剂。几种生物会产生作用于离子通道的小蛋白毒素,帮助猎物捕获或防御。我们建议研究毒素与离子通道TRPV1的相互作用。我们将使用MALDI质谱仪来评估通过反相色谱分离的毒素的分子组成。加州大学旧金山分校的质谱学设施将协助收集以确定分离出的毒素的分子量。
