BAG cochaperone 3
BAG cochaperone 3 (BAG3), also known as BIS, is a stress-responsive HSP70-family co-chaperone involved in protein quality control and proteostasis. This target page groups ABMIUM catalogue reagents for studying BAG3-dependent chaperone responses, selective protein disposal and cellular stress biology.

Research context & evidence
Target information is kept separate from product-level validation so you can review the biology and the reagent evidence independently.
BAG3 binds HSP70-family chaperones through its BAG domain and helps coordinate chaperone-dependent protein quality control. It participates in stress-responsive proteostasis and can connect chaperone-bound clients to selective autophagic disposal pathways, supporting removal of damaged or aggregation-prone proteins.
BAG3 is studied in proteotoxic stress, HSP70-linked chaperone function, protein quality control and chaperone-assisted selective autophagy. Experimental studies often examine BAG3 induction, chaperone association and handling of damaged proteins during cellular stress.
