Rabbit anti-Human STAMBP Polyclonal Antibody

Uniprot Id

O95630

Target Species

Human

Target Name

STAMBP

Target Full Name

STAM-binding protein

Target Function

Zinc metalloprotease that specifically cleaves 'Lys-63'-linked polyubiquitin chains. Does not cleave 'Lys-48'-linked polyubiquitin chains. 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. Has a key role in regulation of cell surface receptor-mediated endocytosis and ubiquitin-dependent sorting of receptors to lysosomes. Endosomal localization of STAMBP is required for efficient EGFR degradation but not for its internalization. Involved in the negative regulation of PI3K-AKT-mTOR and RAS-MAP signaling pathways.

Target Involvement

Microcephaly-capillary malformation syndrome (MICCAP)

Target Subcellular Location

Nucleus. Membrane; Peripheral membrane protein. Cytoplasm. Early endosome.

Target Protein Families

Peptidase M67C family

Target Tissue Specificity

Ubiquitously expressed.

Target Synonyms

AMSH; Associated molecule with the SH3 domain of STAM; Endosome associated ubiquitin isopeptidase; Endosome-associated ubiquitin isopeptidase; MGC126516; MGC126518; MICCAP; STABP_HUMAN; STAM binding protein; STAM-binding protein; Stambp

Target Background

Cytokine-mediated signal transduction in the JAK-STAT cascade requires the involvement of adaptor molecules. One such signal-transducing adaptor molecule contains an SH3 domain that is required for induction of MYC and cell growth. The protein encoded by this gene binds to the SH3 domain of the signal-transducing adaptor molecule, and plays a critical role in cytokine-mediated signaling for MYC induction and cell cycle progression. Multiple alternatively spliced transcript variants encoding the same protein isoform have been found for this gene.
