"The DUBs AMSH (associated molecule with the SH3 domain of STAM) XREF_BIBR and UBPY (ubiquitin isopeptidase Y/ubiquitin specific protease 8) XREF_BIBR, bind both the ESCRT-0 component STAM (signal transducing adaptor molecule) and ESCRT and III complex members XREF_BIBR, and are implicated in regulating EGFR sorting onto the degradative pathway."

"The functional relevance of the interaction between USP8, AMSH, and STAM in the endocytic trafficking of activated growth factors is supported by other observations, including that catalytically inactive AMSH, a potential “substrate trap” mutant, resulted in the accumulation of ubiquitin on endosomes, an increased association with STAM, and the generation of a minor product consistent with ubiquitylated STAM ( xref )."
