FOXO4

Also known as: Forkhead Box O4, FOXO4 Peptide

The native FOXO4 peptide sequence involved in cellular senescence regulation.

Overview

FOXO4 is a forkhead transcription factor involved in cellular stress responses and senescence. The native peptide is studied for its role in the FOXO4-p53 interaction that protects senescent cells. Understanding this interaction led to the development of FOXO4-DRI as a senolytic agent.

Mechanism of Action

FOXO4 binds to p53 in senescent cells, sequestering it in the nucleus and preventing apoptosis. This interaction is what keeps senescent cells alive. Native FOXO4 peptides are used to study this mechanism.

Pharmacokinetics

Native L-amino acid peptide with shorter half-life than DRI version. Susceptible to proteolytic degradation.
