Implementation Constraints

cofactor dependency: cofactor requirement unknownencoding mode: genetically encodedimplementation constraint: context specific validationimplementation constraint: multi component delivery burdenoperating role: sensorswitch architecture: multi component

The method requires SPDM-compatible imaging instrumentation and labeled RNA Pol II targets.; requires super-resolution microscopy setup suitable for SPDM

Uses more than one coordinated component. Independent follow-up evidence is still limited. Validation breadth across biological contexts is still narrow. Independent reuse still looks limited, so the evidence base may be fragile. Multi-component delivery and stoichiometry control can make deployment harder. No canonical validation observations are stored yet, so context-specific performance remains under-specified.

3D-SIM revealed an interchromatin compartment network of channels and wider lacunas that starts at nuclear pores and expands throughout the nuclear space.

Three-dimensional structured illumination microscopy (3D-SIM) demonstrated a network of channels and wider lacunas, called the interchromatin compartment (IC). The IC starts at nuclear pores and expands throughout the nuclear space.
