General annotation (Comments)

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. Ref.1

Subunit structure

Interacts with BCAR1, NEDD9, PTK2/FAK1 and PTPN1 By similarity.

Tissue specificity

Ubiquitously expressed. Found in several cancer cell lines, but not in nonmalignant breast tissue. Ref.1 Ref.2

Sequence similarities

Contains 1 Ras-GEF domain.

Contains 1 SH2 domain.

Ontologies

Alternative products
