Results show that Hsp70 and the Ydj1 and Sis1 Hsp40 proteins accumulated in stress granules and defects in these proteins led to decreases in the disassembly and/or clearance of stress granules.

SSA2p and co-chaperones, SIS1p and YDJ1p, constitute a novel system for tRNA import into the nucleus.
Title: Cytosolic Hsp70 and co-chaperones constitute a novel system for tRNA import into the nucleus.

Interaction of Sis1 with EEVD(Hsp70) minimizes transfer of Sis1-bound clients to Hsp70s that are primed for client transfer to folding and translocation pathways by their preassociation with EEVD binding adaptor proteins.
Title: Roles of intramolecular and intermolecular interactions in functional regulation of the Hsp70 J-protein co-chaperone Sis1.

Sis1 plays a role in prion replication.
Title: Hsp40s specify functions of Hsp104 and Hsp90 protein chaperone machines.

This conservation of function is also prion-variant dependent, indicating that only one of the two Sis1-prion functions may have been maintained in eukaryotic chaperone evolution.
Title: Functional diversification of hsp40: distinct j-protein functional requirements for two prions allow for chaperone-dependent prion selection.
