  • Target

    • Function

      Possible docking protein which may play a role for tyrosine-kinase-based signaling related to cell adhesion. Regulates FAK activity, focal adhesion integrity, and cell spreading.
    • Tissue specificity

      Expressed abundantly in lung and spleen. Also highly expressed in ovarian and leukemia cell lines.
    • Sequence similarities

      Belongs to the CAS family.
      Contains 1 SH3 domain.
    • Post-translational

      Phosphorylated on tyrosines by SRC.
    • Cellular localization

      Cytoplasm > cytoskeleton. Cell junction > focal adhesion.
