This volume discusses the cellular and molecular techniques used to study and characterize the different components of the CRAC channel signaling pathway. The chapters in this book cover topics such as fluorescence-based measurements of the CRAC channel activity in cell populations; patch-clamp recording of the CRAC channel in STIM-Orai overexpressing cells and native systems; western-blotting and co-immunoprecipitation of endogenous STIM/ORAI and protein partners; shRNA-mediated gene silencing; and the SC-SMD system. Written in the highly successful series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Thorough and cutting-edge, is a valuable resource for any researcher interested in learning more about the CRAC channel, as its activation mechanism and roles in cellular functions have yet to be completely explored. weiterlesen
