Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
OptoMYPT is a blue-light-controlled multi-component optogenetic switch that couples the PP1c-binding domain of MYPT1 to an optogenetic dimerizer to recruit endogenous protein phosphatase 1c to the plasma membrane. This recruitment induces dephosphorylation of myosin regulatory light chains and reduces actomyosin contractile force.
Usefulness & Problems
Why this is useful
OptoMYPT enables acute optical relaxation of actomyosin contractility by controlling endogenous PP1c localization with light. In the cited study, this allowed perturbation of cortical tension during cytokinesis and revealed that relaxing cortical tension at both poles accelerates furrow ingression.

Problem solved
This tool addresses the need for spatiotemporal manipulation of myosin II-dependent contractility without directly engineering the endogenous phosphatase catalytic subunit. It specifically provides a way to decrease cortical tension through light-dependent membrane recruitment of endogenous PP1c and consequent myosin regulatory light chain dephosphorylation.

Need inducible protein relocalization or recruitment
DerivedOptoMYPT is a light-controlled, multi-component switch that fuses the PP1c-binding domain of MYPT1 to an optogenetic dimerizer to recruit endogenous protein phosphatase 1c to the plasma membrane.

OptoMYPT is implemented by fusing the PP1c-binding domain of MYPT1 to an optogenetic dimerizer to achieve light-dependent recruitment of endogenous PP1c to the plasma membrane. The available evidence supports blue-light activation and membrane recruitment, but does not specify the dimerizer system, host cells, or cofactor requirements.
The supplied evidence is limited to a single 2021 study and focuses on cytokinesis-related cortical tension, so validation breadth is narrow. The exact optogenetic dimerizer, construct architecture, illumination parameters, and performance metrics are not provided in the supplied evidence.

Comparisons
Source-backed strengths
The reported system acts through endogenous PP1c recruitment, linking optical input to a defined biochemical output: myosin regulatory light chain dephosphorylation. It was functionally validated by decreased actomyosin contractile force and by a cytokinesis phenotype in which pole relaxation accelerated furrow ingression.
Compared with Cry2/CIB
OptoMYPT and Cry2/CIB address a similar problem space because they share localization, recombination.
Shared frame: same top-level item type; shared target processes: localization, recombination; shared mechanisms: heterodimerization; same primary input modality: light
Relative tradeoffs: appears more independently replicated; looks easier to implement in practice.
