Also known as: Arabidopsis CRY2, CRY2 photosensory domain

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

Summary

The Arabidopsis CRY2 photosensory domain is a light-responsive protein domain from plant cryptochrome-2 whose active-state crystal structure was determined in a tetrameric form. Structural analysis indicates that this domain undergoes photo-induced oligomerization and contains specific structural elements and residues that participate in activation.

Usefulness & Problems

Why this is useful

This domain is useful as a structurally characterized light-responsive module for studying and potentially exploiting cryptochrome photoactivation. The available evidence specifically supports its value for understanding how light drives assembly of an active tetrameric state and how activation-related residues and structural elements contribute to that process.

Problem solved

It helps address the problem of defining the structural basis of plant cryptochrome activation under light. The cited study specifically resolves the photosensory domain in a tetrameric active state and identifies features implicated in photo-induced oligomerization.

The available evidence identifies this tool specifically as the photosensory domain of Arabidopsis CRY2 and supports its use as a light-responsive protein domain. However, the provided material does not specify construct boundaries, cofactors, illumination wavelengths, expression systems, or delivery considerations.

The supplied evidence is limited to a single 2020 structural study and does not provide quantitative performance data, spectral parameters, kinetics, or application benchmarks in engineered systems. Evidence for regulation by interacting proteins is described as a proposed model rather than direct functional validation in the provided text.
