Summary: Acts upstream of or within T cell activation via T cell receptor contact with antigen bound to MHC molecule on antigen presenting cell and positive regulation of cell adhesion. Located in cytosol and plasma membrane. Part of T cell receptor complex. Is expressed in several structures, including brain; genitourinary system; hemolymphoid system; liver; and molar. Orthologous to human APBB1IP (amyloid beta precursor protein binding family B member 1 interacting protein). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

These data identify the requirement of RIAM for formation of immunological synapses and in resulting T cell functions in autoimmunity.
Title: Cutting Edge: Loss of T Cell RIAM Precludes Conjugate Formation with APC and Prevents Immune-Mediated Diabetes.
we show that leukocyte integrin activation critically depends on RIAM both in vitro and in vivo
Title: Loss of the Rap1 effector RIAM results in leukocyte adhesion deficiency due to impaired β2 integrin function in mice.
These in vivo results confirm a role for RIAM in the regulation of some, but not all, leukocyte integrins and suggest that RIAM-regulated integrin activation is required for trafficking of lymphocytes
Title: Rap1 and its effector RIAM are required for lymphocyte trafficking.

crystal structure of an active, GTP-bound GTPase domain of Rap1 in complex with the Ras association (RA)-pleckstrin homology (PH) structural module of RIAM at 1.65 A, is reported.

Title: Rap1-GTP-interacting adaptor molecule (RIAM) is dispensable for platelet integrin activation and function in mice.
As talin engages F-actin, force exerted on the R2R3 helical bundles disrupts RIAM binding and exposes the vinculin binding sites, which recruit vinculin to stabilize the complex.
Title: RIAM and vinculin binding to talin are mutually exclusive and regulate adhesion assembly and turnover.
Data demonstrate a novel mechanism by which alphavbeta3 integrin acts to locally suppress beta1 integrin activation and regulate VASP and RIAM to control cell adhesion and migration.
Title: Alpha v beta3 integrin spatially regulates VASP and RIAM to control adhesion dynamics and migration.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
