Influences of Mpl and CRTDel52-D165K and CRTDel52-D166K mutations upon CRTDel52 multimerization. (A–C) HEK293T cells were transiently transfected with plasmids encoding CRTDel52 alone or in combination with His-FLAG Mpl or His-FLAG Mpl alone (A and B) or untagged full-length CRTDel52, CRTDel52-D165K, CRTDel52-D166K, or CRTDel52-3CA (CRTDel52(C163A/C400A/C404A)) or a control vector (Vec; C). Cell lysates from indicated cells were separated by SDS-PAGE under reducing (8% gels) or nonreducing (4–20% gradient gels) conditions or by native-PAGE (8% gels) and immunoblotted with anti-FLAG or anti-CRT(Cmut) antibodies. In blots following SDS-PAGE under nonreducing and native conditions, species consistent with the size of mutant CRT monomers, dimers, and multimers are indicated. Location of loading wells is also indicated. Data are representative of two sets of analyses. MW, molecular weight.
