Construct Pattern·Research·Since 2022

Also known as: red calmodulin fusion protein

Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.

Summary

Development of mice expressing optogenetic sensors (green calmodulin fusion protein (GCaMP), red calmodulin fusion protein (RCaMP)) has allowed visualization of Ca2+ signalling behaviours in a cell specific manner.

Usefulness & Problems
