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.
Specificity
Natural and recombinant Human STAM-binding protein
Subcellular Location
Nucleus Membrane Peripheral membrane protein Cytoplasm Early endosome
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.
