"Both AMSH and Usp8 bind components of the endosomal sorting complex for transport (ESCRT) which are involved in targeting ubiquitinated cargo receptors for incorporation into intraluminal vesicles (IL[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

"The interaction of the two endosomal DUBs, AMSH, and USP8 (UBPY in yeast), with a UIM-containing signal transducing adaptor molecule 2 (STAM2) enhances their deubiquitinating efficacy via substrate arrest [ xref , xref ]."

reach
"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."

sparser
"AMSH and USP8 can also interact with CHMP proteins that are components of the late ESCRT-III machinery xref , xref ."

reach
"The competitive binding of AMSH and USP8 to ESCRT subunits, and the fact that they associate with both ESCRT-0 and -III, suggests that these DUBs may regulate cargo deubiquitination in complex ways."

"AMSH and Usp8 bind with their PxxP motif to the non-canonical SH3-binding motif of ESCRT-0 protein STAM, and with their MIT (Microtubule Interacting and Transport)-domain to several CHMP proteins of t[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

STAM binds USP8 and STAMBP. 5 / 5

sparser
"The molecular mechanism underlying these opposing effects is hinted at by the observation that USP8 and AMSH bind a central SH3 domain of STAM proteins in a mutually exclusive manner ( xref )."

sparser
"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 )."

sparser
"This also contains the sequence PPPRPTAPKP, which binds the Mona SH3 domain [ 39 ] and closely resembles the PXXXRXXKP motifs in UBPY [ 21, 28 ] and AMSH [ 20 ] that bind STAM SH3."

"AMSH (a JAMM family member with specificity for K63 chains) and USP8 associate with STAM proteins, a component of the ESCRT-0 complex xref , xref ."

sparser
"Both AMSH and Usp8 bind to ESCRT-0 protein STAM through a non-canonical SH3-binding motif, and with their MIT-domain to several CHMP proteins of the ESCRT-III machinery [30,37,39,40] ."

STAM binds USP8, STAMBP, and HRS. 1 / 1

sparser
"Ubiquitylation is a highly dynamic process, and Ub is ultimately removed from cargoes prior to MVB vesicle incorporation by the deubiquitylating ESCRT enzymes, UBPY or AMSH, which interact with both the HRS:STAM adaptor and ESCRT-III subunits ( xref , xref )."
STAM binds USP8, STAMBP, and HGS. 1 / 1

"UBPY and AMSH interact with the Hrs-STAM complex and counteract ubiquitination of RTKs."

"Like Doa4 in yeast, mammalian Usp8 and AMSH associate with class E Vps proteins on endosomes."

"CHMP1 (Did2), CHMP2 (Vps2) and CHMP3 (Vps24) can interact with two mammalian deubiquitinating enzymes, AMSH and UBPY, to facilitate their recruitment directly [ xref , xref , xref ]."

"To test this idea, we assayed whether the CHMP4C peptide could competitively inhibit AMSH, MITD1 and USP8 MIT binding to labeled CHMP4B ( xref )."

sparser
"This was surprising, particularly as MITD1, USP8, and AMSH all bound the other two CHMP4 paralogs, CHMP4A and CHMP4B ( xref )."
