This family consists of the C terminal region of the DnaJ protein. It is always found associated with Pfam:PF00226 and Pfam:PF00684. DnaJ is a chaperone associated with the Hsp70 heat-shock system involved in protein folding and renaturation after stress. The two C-terminal domains CTDI and CTDII, both incorporated in this family are necessary for maintaining the J-domains in their specific relative positions [2]. Structural analysis of PDB:1nlt shows that PF00684 is nested within this DnaJ C-terminal region [3].	Domain
