General annotation (Comments)

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. Ref.7
Subunit structure	Interacts with CBL. Part of a complex containing CBL and activated EGFR. Interacts with ubiquitin and with mono-ubiquitinated proteins. Ref.7
Subcellular location	Cytoplasm By similarity. Nucleus Potential.
Sequence similarities	Contains 1 SH3 domain. Contains 1 UBA domain.
