(A) Co-IP of HA-tagged PLEKHM1 and FLAG-tagged DEF8, KIFc1, CLASP2, and TPX2 in 293-T cells. The lysate of empty vector expressing 293-T cell (lane 1) served as a negative control. TCL, total cell lysate. (B) The structural domains of murine PLEKHM1 and DEF8. The numbers indicate the positions of amino acids. (C and D) Co-IPs of MYC-tagged DEF8, FLAG-tagged RAB7, and HA-tagged PLEKHM1 or PLEKHM1 with Y949A/L950A double mutation in 293-T cells. The experiments were repeated 3 times.
