... of clathrin-dependent endocytosis, which are known to arrest the progression of endocytosis at coated-pit stages, inhibit internalization of cell-surface-bound TGFβ and promote colocalization and accumulation of TβR-I and SARA at the plasma membrane. These inhibitors enhance TGFβ-induced signaling...

... coated pits upon receptor stimulation. Similarly, in RBL-2H3 cells that stably express physiological levels of m1AChR, the addition of carbachol selectively induces the localization of arrestin-3, but not arrestin-2, to coated pits. Thus, this work demonstrates coupling of G proteincoupled receptors...

... that they are predominantly in different locations, indicating a role for the lumenal domain of the MPR in determining the steady-state distribution of the MPR itself. * Author for correspondence 18 10 1993 03 01 1993 © 1994 by Company of Biologists 1994 trans -Golgi network coated pit...
