FK506-binding protein 4 (FKBP52)

Target
FKBP52
Molecular classification
Immunophilin, Peptidyl-prolyl cis-trans isomerase, Chaperone
01

Overview

FK506-binding protein 4 (FKBP52) is an immunophilin family member with peptidyl-prolyl cis-trans isomerase (PPIase) activity. It functions as a molecular chaperone, interacting with heat shock proteins (Hsp90 and Hsp70) and steroid hormone receptors, influencing protein folding, trafficking, and signaling pathways. It is implicated in neuroprotection and regulation of microtubule dynamics. Recent research suggests its potential as a biomarker and therapeutic target in Alzheimer's disease.
