Together, the results presented here demonstrate that PTP1B can influence RTK signaling in a previously unrecognized manner. We show that PTP1B directly targets STAM2, part of the ESCRT-0 endosomal sorting complex, and we provide the first evidence that tyrosine phosphorylation affects STAM localization and function. This regulatory mechanism could impact signaling downstream of numerous cell surface receptors that are ubiquitinated and recognized by this conserved sorting machinery. |
