  • 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.
  • Sequence similarities

    Contains 1 SH3 domain.
    Contains 1 UBA domain.
  • Cellular localization

    Cytoplasm. Nucleus.
