DnaJ homolog subfamily C member 3 is a protein that in humans is encoded by the DNAJC3 gene.[1][2][3]

The protein encoded by this gene contains multiple tetratricopeptide repeat (TPR) motifs as well as the highly conserved J domain found in DNAJ chaperone family members. It is a member of the tetratricopeptide repeat family of proteins and acts as an inhibitor of the interferon-induced, dsRNA-activated protein kinase (PKR).[3]


DNAJC3 has been shown to interact with Protein kinase R,[4][5] PRKRIR[5] and EIF2AK3.[6]
