Rab27a mutation at R82C selectively disrupts binding to Munc13-4, but not melanophilin (MLPH). tGFP-tagged Rab27a wild-type (WT), D74H and R82C were expressed in mel1106 (A) and NK92 (B). Cells were lysed in CHAPS buffer and lysates incubated first with isotype control-coated beads (clone MPC-11) and subsequently with anti-tGFP-coated beads (clone 2H8). Whole cell lysates and precipitates were separated in SDS-PAGE (4-12%), proteins transferred onto nitrocellulose membrane and the membrane probed with anti-Rab27a (clone 1G7) and anti-MLPH (A) or anti-Munc13-4 (B) antibodies (n=3).
