Protein electrophoresis figures. A, SDS-PAGE analysis of L.c-MRC1 and L.c-MRC2 proteins; B, SDS-PAGE analysis of precipitated L.c-MRC1 and L.c-MRC2 proteins (the black arrows indicate the target protein bands. The target protein is detected in the precipitate); C, Purified L.c-MRC1 and L.c-MRC2 proteins. The black arrows indicate the target protein bands.
Fig. 5.
3D protein structures of L.c-MRC1-C and L.c-MRC2-C. These protein structures were predicted using SWISSMODEL. The N-terminus is blue and the C-terminus is red (for interpretation of the references to color in this figure legend, the reader is referred to the web version of this article).
