Genetically encoded calcium indicator polypeptides and nucleic acids encoding same

摘要

Provided herein are nucleic acid sequences and polypeptides encoding a genetically encoded calcium indicator (GECI). Also provided are vectors and cells comprising the nucleic acid sequences and/or polypeptides. Kits comprising the nucleic acid sequences, polypeptides, vectors, cells and combinations thereof are also provided. Also provided herein are methods of screening for G-protein coupled receptor (GPCR) agonists and antagonists and methods of monitoring neural activity using the GECIs.
