Biological background
Protein function (datasheet): 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. .
Scientific background (datasheet): APBB1IP (APBB1-Interacting Protein), also called RIAM or RARP1, is a protein that in humans is encoded by the APBB1IP gene. By genomic sequence analysis, Lafuente et al. (2004) mapped the RIAM gene to chromosome 10p12.1. Using promoter-reporter gene assays, Inagaki et al. (2003) found that RARP1 suppressed transcription from AP1 and SRE sites, but not CRE sites, in all cell lines examined. The proline-rich regions of RARP1 suppressed AP1 transactivation. Lafuente et al. (2004) found that RIAM interacted with profilin and VASP, molecules that regulate actin dynamics, as well as with RAP1-GTP.
Cellular localization (datasheet): Cell membrane ; Peripheral membrane protein . Cell projection, lamellipodium . Cell junction, focal adhesion . Cytoplasm, cytoskeleton . 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 details (datasheet): Widely expressed with high expression in thymus, spleen, lymph node, bone marrow and peripheral leukocytes. .
Sequence similarities (datasheet): Belongs to the MRL family.
Research relevance and current trends
- Commonly studied in contexts related to Developmental Families,Domain Families,Epigenetics and Nuclear Signaling,Lineage Markers,Lineage Specification,Neurogenesis,Neurology Process,Neuroscience,Oncoproteins,Oncoproteins/Suppressors,Stem Cells,Transcription,Transcription Factors.
- Supports comparative expression analysis across conditions, genotypes, or treatments when paired with appropriate controls.
- Useful for confirming target presence and subcellular distribution using orthogonal readouts (e.g., microscopy vs. immunoblotting).
Common research applications
- Western blot (WB): Compare relative target abundance and apparent size/isoforms across samples; interpret bands in light of expected MW and potential PTMs.
- ELISA: Measure target abundance in compatible matrices using a standard-curve readout; ensure dilution linearity and appropriate controls.
- Immunohistochemistry (IHC): Assess tissue distribution and cell-type patterns; interpret staining with appropriate negative controls and antigen context.
- Immunofluorescence / ICC: Visualize subcellular localization and co-localization patterns; consider fixation/permeabilization compatibility and controls.
- Flow cytometry: Quantify target-positive populations in single-cell suspensions; pair with viability and isotype/FMO controls conceptually.
Notes for experimental interpretation
- Consider isoforms, post-translational modifications, and processing that can shift apparent molecular weight or localization.
- Cross-reactivity (datasheet): No cross-reactivity with other proteins
- Use appropriate positive and negative controls (e.g., KO/KD, blocking peptide, or isotype controls) to support specificity interpretation.
As a polyclonal antibody, this reagent may recognize multiple epitopes on the target, which can improve detection robustness but may require careful specificity controls.
