Implementation Constraints
cofactor dependency: cofactor requirement unknownencoding mode: genetically encodedimplementation constraint: context specific validationimplementation constraint: payload burdenoperating role: sensor
They require live-cell expression or introduction of the probe constructs and an imaging-compatible optical assay. The payload does not provide more detailed assay prerequisites.; requires expression or deployment of mini G probe constructs in live cells; requires optical imaging-compatible assay setup
The provided evidence does not show that mini G probes alone capture every downstream second messenger or all aspects of heterotrimeric G-protein activation. They are presented as receptor-activity probes rather than complete pathway reporters.; the provided payload does not specify subtype coverage, sensitivity, or caveats
