DnaJ homolog subfamily C member 11 is a protein that in humans is encoded by the DNAJC11 gene. DNAJC11 is a member of the J proteins also known as HSP40 family of co-chaperones. Recently DNAJC11 has been found to interact with mitofilin, a mitochondrial inner membrane protein, indicating that it may be a molecular chaperone during mitochondrial protein import and folding.
