function:May act as an adapter protein and couple activated growth factor receptors to a signaling pathway that regulates the proliferation in breast cancer cells. When overexpressed, it confers anti-estrogen resistance in breast cancer cell lines. May also be regulated by cellular adhesion to extracellular matrix proteins.,PTM:Phosphorylated on tyrosine.,similarity:Contains 1 Ras-GEF domain.,similarity:Contains 1 SH2 domain.,subunit:Interacts with BCAR1, NEDD9, PTK2 and PTPN1.,tissue specificity:Ubiquitously expressed. Found in several cancer cell lines, but not in nonmalignant breast tissue.,
Cytoplasm . Cell junction, focal adhesion . Localization to focal adhesions depends on interaction with PTPRA. .
Ubiquitously expressed. Found in several cancer cell lines, but not in nonmalignant breast tissue.
