"overexpressing DNAJA2 but not DNAJA1 enhanced CFTR degradation at the endoplasmic reticulum by Hsc70/Hsp70 and the E3 ubiquitin ligase CHIP. Excess Hsp70 also promoted CFTR degradation but this occurred through the lysosomal pathway and required CHIP but not complex formation with HOP and Hsp90."xsd:string
