Extended Data Fig. 4: Attachment of YFP had no effect on BiP functionality.
From: UPR proteins IRE1 and PERK switch BiP from chaperone to ER stress sensor

(a) ATPase activity of BiP and YFP tagged BiP. (b) Comparison of the rate of ATPase activity for BiP and YFP- tagged BiP on addition of co-chaperones and CFP-IRE1 LD. The attachment of YFP had no effect on BiP basal activity, or stimulation by co-chaperones, or inhibition by CFP tagged IRE1 LD. Statistics as in Fig. 1, source data available online.
