Peptidyl Arginine Deiminase 2 (PADI2)

Target
PADI2
Molecular classification
Enzyme, Peptidyl arginine deiminase
01

Overview

Peptidyl arginine deiminase 2 (PADI2) is an enzyme that catalyzes the conversion of protein-bound arginine residues into citrulline. It requires calcium ions for enzymatic activity and is involved in myelination, immune regulation, and gene expression. PADI2 is implicated in diseases like multiple sclerosis, rheumatoid arthritis, and cancer, making it a potential drug target.
