TRIM21-nanobody chimeras
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
TRIM21-nanobody chimeras are engineered Trim-Away constructs that fuse TRIM21 activity to nanobody-based target recognition. In the cited 2020 work, these chimeras were described as highly active and were further adapted for optogenetic control of targeted protein degradation.
Usefulness & Problems
Why this is useful
These constructs expand the Trim-Away toolbox by coupling TRIM21-mediated degradation to nanobody-directed substrate recognition. The same study indicates that they can be placed under optogenetic control, supporting temporally controlled degradation applications.
Source:
Here we show that a mechanism of substrate-induced clustering triggers intermolecular dimerization of the RING domain to switch on the ubiquitination activity of TRIM21 and induce an antiviral response or drive Trim-Away.

We harness this mechanism to expand the Trim-Away toolbox with highly-active TRIM21-nanobody chimeras that can also be controlled optogenetically.
Problem solved
They address the problem of directing TRIM21 ubiquitination activity toward chosen protein targets without relying solely on conventional antibody delivery formats. The cited work also positions them as a way to control targeted degradation with light, although detailed operating parameters are not provided in the supplied evidence.

The construct pattern is supported by domain fusion between TRIM21 and a nanobody, with optional optogenetic control modules mentioned in the source text. Beyond that, the evidence does not provide construct architecture, expression system, cofactor requirements, or delivery details.
The supplied evidence does not specify the nanobody targets, degradation kinetics, light wavelengths, dynamic range, or cellular contexts tested for the chimeras. Independent replication is not provided in the evidence set, and optogenetic implementation details are not described.
