Protein Family Models

DNA-J related domain-containing protein consists of an N-terminal DNA-J related domain and C-terminal J domain (also known as DnaJ domain); similar to molecular chaperone DnaJ, a protein that plays crucial roles in protein translation, folding, unfolding, translocation, and degradation, primarily by stimulating the ATPase activity of Hsp70

This domain family is found in bacteria, and is approximately 130 amino acids in length. The family is found in association with Pfam:PF00226. There is a conserved YYLD sequence motif. Mostof the sequences in this family are annotated as DNA-J related proteins but there is little publication to back this up. (from Pfam)

DnaJ domains (J-domains) are associated with hsp70 heat-shock system and it is thought that this domain mediates the interaction. DnaJ-domain is therefore part of a chaperone (protein folding) system. The T-antigens, although not in Prosite are confirmed as DnaJ containing domains from literature [2]. [1]. 8016869.
