Recombinant Human Ubiquitin-associated and SH3 domain-containing protein B (UBASH3B)

Uniprot Id

Q8TF42

Target Species

Human

Target Name

UBASH3B

Target Full Name

Ubiquitin-associated and SH3 domain-containing protein B

Target Function

Interferes with CBL-mediated down-regulation and degradation of receptor-type tyrosine kinases. Promotes accumulation of activated target receptors, such as T-cell receptors and EGFR, on the cell surface. Exhibits tyrosine phosphatase activity toward several substrates including EGFR, FAK, SYK, and ZAP70. Down-regulates proteins that are dually modified by both protein tyrosine phosphorylation and ubiquitination.

Target Subcellular Location

Cytoplasm. Nucleus.

Target Background

This gene encodes a protein that contains a ubiquitin associated domain at the N-terminus, an SH3 domain, and a C-terminal domain with similarities to the catalytic motif of phosphoglycerate mutase. The encoded protein was found to inhibit endocytosis of epidermal growth factor receptor (EGFR) and platelet-derived growth factor receptor.
