Diaphanous Autoregulatory Domain from mDia1

Protein Domain·Research·Since 2013

Also known as: isolated Diaphanous Autoregulatory Domain from mDia1

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

Summary

The Diaphanous Autoregulatory Domain from mDia1, in this tool context, is an optogenetic fusion between the Avena sativa Phototropin1 LOV2 domain and an isolated mDia1 DAD. Blue light uncages the DAD, enabling rapid activation of endogenous diaphanous-related formins and acute actin cytoskeletal remodeling.

Usefulness & Problems

Why this is useful

This tool is useful for temporally precise optical control of endogenous diaphanous-related formin activity rather than overexpressing full-length actin regulators. In the reported study, photoactivation induced filopodia and lamellipodia formation and increased F-actin along existing stress fibers within minutes.

Source:

We have developed an optogenetic technique for the activation of diaphanous-related formins. Our approach is based on fusion of the light-oxygen-voltage 2 domain of Avena sativa Phototrophin1 to an isolated Diaphanous Autoregulatory Domain from mDia1.

demonstrate the utility of photoactivatable diaphanous autoregulatory domain for the study of diaphanous-related formin function in cells

Problem solved

It addresses the problem of acutely activating endogenous diaphanous-related formins with light while keeping the construct inactive in the dark. The reported application also enabled interrogation of how formin-driven F-actin accumulation relates to stress-fiber contractility.

Derived

This tool is an optogenetic fusion of the Avena sativa Phototropin1 LOV2 domain to an isolated Diaphanous Autoregulatory Domain (DAD) from mDia1. Blue-light activation uncages the DAD and rapidly activates endogenous diaphanous-related formins, producing acute actin cytoskeletal remodeling.

The construct is based on domain fusion of the Avena sativa Phototropin1 LOV2 domain to an isolated mDia1 Diaphanous Autoregulatory Domain. Its input modality is blue light, and the reported design relies on light-dependent uncaging of the DAD to activate endogenous diaphanous-related formins. No additional implementation details such as expression system, linker design, or cofactor requirements are provided in the supplied evidence.

The available evidence is from a single 2013 study and focuses on cytoskeletal phenotypes, with limited information here on quantitative dynamic range, reversibility, or cell-type breadth. The mechanistic conclusion about decoupling between F-actin accumulation and contractility is presented as an interpretation rather than a universally established property.

Comparisons

Source-backed strengths

The reported construct was inactive in the dark and rapidly activated endogenous diaphanous-related formins under blue light. In cells, activation produced fast, observable actin remodeling, including filopodia, lamellipodia, and increased F-actin along stress fibers within minutes. The study further reported stress-fiber thickening without an increase in contractility.
