|Target/Specificity||A synthetic peptide corresponding to residues in human RIAM was used as an immunogen.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||RIAM Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Synonyms||PREL1, RARP1, RIAM|
|Function||Appears to function in the signal transduction from Ras activation to actin cytoskeletal remodeling. Suppresses insulin- induced promoter activities through AP1 and SRE. Mediates Rap1- induced adhesion.|
|Cellular Location||Cell membrane; Peripheral membrane protein. Cell projection, lamellipodium. Cell junction, focal adhesion Cytoplasm, cytoskeleton. Note=Colocalizes with ENA/VASP proteins at lamellipodia tips and focal adhesions, and F- actin at the leading edge. At the membrane surface, associates, via the PH domain, preferentially with the inositol phosphates, PtdIns(5)P and PtdIns(3)P. This binding appears to be necessary for the efficient interaction of the RA domain to Ras-GTPases (By similarity).|
|Tissue Location||Widely expressed with high expression in thymus, spleen, lymph node, bone marrow and peripheral leukocytes|

RIAM (a Rap1-GTP-interacting adapter molecule) defines a family of adaptor molecules that contain a RA-like (Ras association) domain, a PH (pleckstrin homology) domain, and various proline-rich motifs (1). RIAM directly binds to Ena/VASP proteins, important modulators of cell migration that localize to focal adhesions and stress fibers, and co-localizes with them at focal adhesions in response to Ras activation. Moreover, RIAM directly binds to activated Ras in a phosphoinositide-dependent manner. RIAM is believed to be the first direct link between Ras signalling and cytoskeletal remodelling via Ena/VASP proteins during cell migration and spreading (2).
