Actin Force Sensor (cpstFRET) Expressing Cell Lines
These cell lines express actin force probes, allowing for the measurement of forces of actin and actinin in living cells via simple anisotropy FRET ratio R to measure changes in FRET.
Highlights:
- Integrate naturally into cellular microfilaments
- Report force in actin and the actin cross-linker actinin
- Available as immortalized HEK293 or MDCK cell lines
Available Versions:
- AcpA - One actin molecule attached on each end of cpstFRET
- cpA - One actin molecule attached to the C-terminal of cpstFRET, leaving the other end of the probe dangling free and the probe devoid of tension. (force-free control)
- M-cpstFRET - Actinin with the sensor incorporated between spectrin repeat domains 3 and 4 toward the middle of actinin
- C-cpstFRET - C-terminal–tagged actinin (force-free control)
Mechanical signaling plays many roles in cell physiology, including stem cell differentiation and reprogramming. The actin force probe, named actin–cpstFRET (circularly permuted stretch sensitive FRET)–actin (AcpA), consists of a dipole orientation-based FRET sensor called cpstFRET flanked with β-actin monomers. The sensor consists of a pair of tandemly connected circularly permutated CFP/YFPs. Once expressed in cells, the actin probes incorporate into mainly into f-actin filaments and allow for the measurement of forces of actin and actin in in living cells via simple anisotropy FRET ratio R to measure changes in FRET.
