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].	Domain
A, B, C, D	PF07743	HSCB C-terminal oligomerisation domain (HSCB_C)	HSCB C-terminal oligomerisation domain	This domain is the HSCB C-terminal oligomerisation domain and is found on co-chaperone proteins.	Domain
