I-BAR domain

Protein Domain·Research·Since 2022

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

Summary

The I-BAR domain is used as a component of CRY-BARs, a family of light-gated I-BAR-domain-containing tools designed for remodeling membrane architecture. In this context, the domain contributes to optogenetic control of membrane-associated cellular dynamics and membrane protrusion-related processes.

Usefulness & Problems

Why this is useful

Within CRY-BARs, the I-BAR domain is useful for building light-responsive tools that remodel membrane architectures and control cellular dynamics. The reported applications include use in cell lines and primary neuron cultures to report membrane dynamic changes associated with cellular activity.

Input: Light

Implementation Constraints

The reported implementation is through design of light-gated I-BAR-domain-containing fusion tools termed CRY-BARs. Beyond the fact that these are light-gated and were used in cell lines and primary neuron cultures, the supplied evidence does not provide additional practical details on cofactors, expression systems, or construct configuration.

The supplied evidence concerns the I-BAR domain only in the context of CRY-BAR fusion tools rather than as a standalone domain. The source text provided here does not specify quantitative performance, illumination parameters, construct architecture details, or direct independent replication.
