re-engineered MLKL membrane recruitment tool

Multi-Component Switch·Research·Since 2022

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

Summary

The re-engineered MLKL membrane recruitment tool is a single-component optogenetic system derived from MLKL that preserves light-mediated plasma membrane recruitment while blocking MLKL-associated cell-killing activity. It is intended to modulate protein function through light-controlled localization at the plasma membrane.

Usefulness & Problems

Why this is useful

This tool provides optical control over protein localization at the plasma membrane using an MLKL-derived single-component design. It is useful where plasma membrane recruitment is desired without the confounding cytotoxicity associated with native or death-inducing light-activated MLKL variants.

Problem solved

It addresses the problem that MLKL-based light activation can couple membrane recruitment to rapid cell death. The re-engineered variant separates light-mediated plasma membrane recruitment from MLKL cell-killing capacity.

Problem links

Need inducible protein relocalization or recruitment

Derived

The re-engineered MLKL membrane recruitment tool is a single-component optogenetic system derived from MLKL that retains light-mediated plasma membrane recruitment while blocking MLKL-associated cell-killing activity.

The tool is based on engineered MLKL domains and is described as single-component. The available evidence supports light-mediated plasma membrane recruitment, but does not specify construct architecture, illumination parameters, expression system, or cofactor requirements.

The supplied evidence does not report quantitative performance metrics, kinetics, reversibility, wavelength dependence, or validation across multiple cargos or cell types. Independent replication is not provided in the supplied evidence.
