Selective control of basolateral membrane protein polarity by cdc42.

Abstract excerpt

The rho GTPase cdc42 is implicated in several aspects of cell polarity. A recent study (Kroschewski R, Hall A, Mellman I. Nat Cell Biol 1999;1:8-13) demonstrated that a dominant negative mutant of cdc42 abolishes the polarity of basolateral membrane proteins in MDCK cells, but did not elucidate whether this effect was selective for basolateral proteins or nonselective for all secreted proteins. To answer this...
