Two ABCC1-HA point mutants, L300A and I301A, displayed a mixed distribution pattern, indicating diminished basolateral targeting specificity.

status: NEW93 In addition to their usual localization to the basolateral membrane, significant proportions of the L300A and I301A mutants were found in the apical vacuoles of every polarized HepG2 cell.

ABCC1 p.Ile301Ala 24129190:93:110
status: NEW94 All other ABCC1 point mutants tested exhibited normal basolateral localization, which excludes the possibility that perturbed localization of the L300A and I301A mutants was caused by gross protein misfolding arising from a point mutation and inhibition of ABCC1 trafficking to the basolateral membrane.

status: NEW103 Similarly, MCCs of the I301A mutant were 0.63 &#b1; 0.05 and 0.59 &#b1; 0.04, respectively, which also suggests a mixed localization of the I301A mutant (Fig. 3C).

status: NEW129 HepG2 cells were transiently cotransfected with 0.5 lg of the wild-type (A), L300A (B), or I301A (C) ABCC1-HA expression plasmids, along with 0.5 lg of empty vector pCMV-HA.
