Multi-Component Switch·Research·Since 2025

Also known as: near-infrared photocleavable dimerization complex-activated split-Cas9/dCas9 system, split-Cas9/dCas9 system

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

Summary

The near-infrared light activatable chemically induced split-Cas9/dCas9 system is a multi-component CRISPR switch in which split Cas9 or dCas9 is activated through a near-infrared photocleavable dimerization complex. It is intended to provide near-infrared light-gated control of CRISPR genome editing-related activity.

Usefulness & Problems

Why this is useful

This system is useful because it aims to control CRISPR activity with near-infrared light rather than UV or blue light. The cited motivation is to improve tissue penetration and reduce the safety concerns associated with UV-dependent light-activatable CRISPR systems.

Source:

To address this, we developed a split-Cas9/dCas9 system in which activation is achieved through a near-infrared photocleavable dimerization complex.

Problem solved

It is designed to address the limitation that most light-activatable CRISPR systems require UV or blue light, which constrains tissue penetration and raises safety concerns. It also targets shortcomings of some longer-wavelength CRISPR systems that are reported to have slow activation or toxicity and biocompatibility issues in humans.

A small number of longer-wavelength CRISPR activation systems are limited by slow activation or toxicity and biocompatibility issues in humans.

A small number of systems that activate CRISPR using longer wavelengths are hindered by either slow light activation or issues related to toxicity and biocompatibility of the proposed techniques in humans.

comparative limitationsupports

Most recently introduced light-activatable CRISPR systems require UV or blue light, which limits tissue penetration and raises safety concerns for UV light.

A drawback is that the overwhelming majority of recently introduced light activatable CRISPR systems require UV or blue light exposure, severely limiting the penetration depth of light in tissue at which CRISPR can be activated, and, in the case of UV light, raising safety concerns.

design intentsupports

Activating CRISPR primarily in targeted cells could minimize off-target effects by reducing unintended genetic modifications in non-target tissues.

These effects could, in principle, be minimized by ensuring that CRISPR is activated primarily in the targeted cells, thereby reducing the likelihood of unintended genetic modifications in non-target tissues.
