USP32 deubiquitinates RAB7A. 3 / 3
| 3

reach
"This suggested that deubiquitylation of Rab7 by USP32 promotes release of Rab7 from the membrane to the cytosol, where a new functional cycle of this Rab can commence (Fig. 5i)."

reach
"Taken together with the observations on endosomal transport (Fig. 6), these findings support a model wherein deubiquitylation of Rab7 by USP32 exerts multifaceted control over membrane dynamics at the LE/MVB by promoting their intracellular motility as well as enabling efficient recycling from these organelles (Fig. 9)."

reach
"Having established that USP32 can deubiquitylate Rab7 in vitro and in situ, we sought to understand the interplay between USP32 and Rab7 in endosome biology."
