Protein Structure

UniProt Annotation

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. {ECO:0000269PubMed:9582273}.

Subcellular Localization

Disease Associations

Tissue Specificity

Ubiquitously expressed. Found in several cancer cell lines, but not in nonmalignant breast tissue. {ECO:0000269PubMed:10187783, ECO:0000269PubMed:9582273}.
