APBB1IP (Amyloid Beta Precursor Protein-Binding Family B Member 1 Interacting Protein): APBB1IP, also known as RIAM (Rap1-GTP-interacting adaptor molecule), plays a critical role in integrin activation, a key process in cell adhesion and migration. By linking Rap1 GTPases to the actin cytoskeleton, APBB1IP facilitates cell adhesion to the extracellular matrix, impacting immune cell function, tumor metastasis, and wound healing. Its role in these processes makes it a subject of interest for research into immune response regulation and cancer....
