14-3-3 Protein

Molecular classification
Scaffolding protein, Adaptor protein
01

Overview

The 14-3-3 protein family is a highly conserved group of regulatory molecules found in eukaryotic cells. Functioning as scaffolding or adaptor proteins, they modulate the activity, localization, and interactions of target proteins, including kinases, phosphatases, transmembrane receptors, and transcription factors. Dysregulation of 14-3-3 proteins is implicated in diseases such as cancer, neurological disorders, rheumatoid arthritis, and viral infections. They represent promising drug targets due to their numerous binding partners and roles in various cellular processes.
