GO:0071818:   BAT3 complex
A protein complex consisting of BAT3 (BAG6) and its cofactors. In mammals these cofactors are TRC35 (GET4) and UBL4A. It facilitates tail-anchored protein capture by ASNA1/TRC4 and also chaperones polypeptides from the endoplasmic reticulum retrotranslocation machinery to the proteasome, maintaining the solubility of substrates to improve ER-associated protein degradation (ERAD).
