KEAP1-based targeted protein degradation, KEAP1-recruiting PROTACs

Extracted Explainers

What the tool is doing

KEAP1-based PROTACs are described as heterobifunctional degraders that harness the ubiquitin-proteasome system by recruiting KEAP1. The review frames them as an emerging therapeutic modality for targeted protein degradation.

Source 1DOI PubMed

What problem it solves

They address the need to diversify the repertoire of E3 ligases available for PROTAC design beyond more established recruiters.

Source 1DOI PubMed

What it does not solve

The abstract states that current challenges remain and that the therapeutic potential is not yet fully realized.

Source 1DOI PubMed

Alternatives

The abstract contrasts different KEAP1 recruiter classes, including short peptides, covalent small molecules such as CDDO derivatives, and non-covalent inhibitors such as KI696.
