ID:STABP_HUMAN DESCRIPTION: RecName: Full=STAM-binding protein; EC=3.4.19.-; AltName: Full=Associated molecule with the SH3 domain of STAM; AltName: Full=Endosome-associated ubiquitin isopeptidase; FUNCTION: Zinc metalloprotease that specifically cleaves 'Lys-63'- linked polyubiquitin chains. Does not cleave 'Lys-48'-linked polyubiquitin chains (By similarity). Functions at the endosome and is able to oppose the ubiquitin-dependent sorting of receptors to lysosomes. Plays a role in signal transduction for cell growth and MYC induction mediated by IL-2 and GM-CSF. Potentiates BMP (bone morphogenetic protein) signaling by antagonizing the inhibitory action of SMAD6 and SMAD7. COFACTOR: Binds 2 zinc ions per subunit (By similarity). ENZYME REGULATION: Inhibited by N-ethylmaleimide. SUBUNIT: Interacts with STAM1. Interacts with SMAD6 and SMAD7. Interacts with CHMP3; the interaction appears to relieve the autoinhibition of CHMP3. Interacts with SMURF2 and RNF11; this interaction promotes ubiquitination. INTERACTION: Q9HD42:CHMP1A; NbExp=3; IntAct=EBI-396676, EBI-1057156; Q7LBR1:CHMP1B; NbExp=5; IntAct=EBI-396676, EBI-2118090; Q9Y3E7:CHMP3; NbExp=5; IntAct=EBI-396676, EBI-2118119; Q9NZZ3:CHMP5; NbExp=2; IntAct=EBI-396676, EBI-751303; P62993:GRB2; NbExp=3; IntAct=EBI-396676, EBI-401755; Q9Y3C5:RNF11; NbExp=2; IntAct=EBI-396676, EBI-396669; O43541-2:SMAD6; NbExp=2; IntAct=EBI-396676, EBI-4324970; Q92783:STAM; NbExp=3; IntAct=EBI-396676, EBI-752333; O75886:STAM2; NbExp=3; IntAct=EBI-396676, EBI-373258; SUBCELLULAR LOCATION: Nucleus. Membrane; Peripheral membrane protein. Cytoplasm. Early endosome. TISSUE SPECIFICITY: Ubiquitously expressed. DOMAIN: The JAMM motif is essential for the protease activity (By similarity). PTM: Phosphorylated after BMP type I receptor activation. PTM: Ubiquitinated by SMURF2 in the presence of RNF11. MISCELLANEOUS: X-ray crystallography studies of STAMBPL1, another member of the peptidase M67C family, has shown that Glu-280 binds zinc indirectly via a water molecule. Nevertheless, this residue is essential for catalytic activity. SIMILARITY: Belongs to the peptidase M67C family. SIMILARITY: Contains 1 MPN (JAB/Mov34) domain.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
