Biological background

Biological context: Cytokine that binds to TNFRSF18/AITR/GITR. Regulates T- cell responses. Can function as costimulator and lower the threshold for T-cell activation and T-cell proliferation. Important for interactions between activated T-lymphocytes and endothelial cells. Mediates activation of NF-kappa-B. Triggers increased phosphorylation of STAT1 and up-regulates expression of VCAM1 and ICAM1 (PubMed:23892569). Promotes leukocyte adhesion to endothelial cells (PubMed:23892569). Regulates migration of monocytes from the splenic reservoir to sites of inflammation (By similarity).

Expression and localization notes: cellular localization: Cell membrane, tissue context: Expressed at high levels in the small intestine, ovary, testis, kidney and endothelial cells..

Common research applications

• Western blotting (WB): Compare RRS1 levels across samples and conditions using appropriate loading and biological controls.
• Immunohistochemistry (IHC): Evaluate spatial distribution of RRS1 in tissue sections, considering fixation and antigen retrieval effects.
• Immunofluorescence / ICC: Assess subcellular localization patterns and co-localization with compartment markers in cultured cells.
• Flow cytometry: Quantify RRS1-positive populations in single-cell suspensions with appropriate gating and controls.
• ELISA: Use antibody-based detection formats to assess antigen presence or binding in plate-based assays.

Notes for experimental interpretation

• Account for isoforms, post-translational modifications, and sample-specific processing that can shift apparent molecular weight or epitope accessibility.
• Use positive/negative biological controls where possible (e.g., known-expressing cells/tissues, knockdown/knockout models) and include appropriate secondary-only/isotype controls for imaging workflows.

Additional product notes (from provided fields)

• Background: Ribosome biogenesis regulatory protein homolog is a protein that in humans is encoded by the RRS1 gene. RRS1 involved in ribosomal large subunit assembly and may regulate the localization of the 5S RNP/5S ribonucleoprotein particle to the nucleolus.
• Cross reactivity: No cross-reactivity with other proteins.
• Cellular localization: Cell membrane
• Tissue details: Expressed at high levels in the small intestine, ovary, testis, kidney and endothelial cells.
• Research category: Cancer,Cardiovascular,Cell Type Markers,Cytokines,Growth Factors,Growth Factors/Hormones,Immunology,Innate Immunity,Signal Transduction,Tags & Cell Markers,TNF Superfamily,Vasculature
