Key elements and design rationale
- Target: SRRT — Zinc finger protein Helios (cytochrome c oxidase subunit 4I1). Alternative names: Cytochrome c oxidase subunit 4 isoform 1, mitochondrial; Cytochrome c oxidase polypeptide IV; Cytochrome c oxidase subunit IV isoform 1; COX IV-1; COX4I1; COX4
- Antibody format: Polyclonal; Rabbit IgG
- Species context: Host: Rabbit, Reactivity: Human,Mouse,Rat
- Purification: Immunogen affinity purified.
- Immunogen: E.coli-derived human ARS2/SRRT recombinant protein (Position: H125-Q793).
- Molecular weight context: observed 101 kDa, calculated 101 kDa (reported)
- Provided application(s): WB, IHC, IF, ICC, Flow, IP, ELISA
These attributes help contextualize how the antibody is commonly selected (host/clonality/isotype/label) and how signals are interpreted across sample types and assay formats.
Biological background
Function: This protein is one of the nuclear-coded polypeptide chains of cytochrome c oxidase, the terminal oxidase in mitochondrial electron transport.
Cellular localization: Mitochondrion inner membrane.
Tissue details: Ubiquitous.
Background: Serrate RNA effector molecule homolog (SRRT) also known as arsenite-resistance protein 2 (ARS2) is a protein that in humans is encoded by the SRRT gene. Enables mRNA cap binding complex binding activity and protein-macromolecule adaptor activity. Involved in primary miRNA processing. Located in nucleoplasm. Part of ribonucleoprotein complex.
Cross reactivity: No cross-reactivity with other proteins.
Research relevance and current trends
- Quantitative and spatial profiling: expression patterns are increasingly studied across cell states using multiplex imaging and omics-informed validation.
- Isoforms and post-translational modifications: researchers often evaluate how isoform composition and PTMs can shift apparent molecular weight or localization.
- Context-aware interpretation: comparative studies commonly include perturbations (stimulation, inhibition, genetic models) to relate target changes to pathway behavior.
Common research applications
- Western blot (WB): compare relative target abundance and apparent size shifts (e.g., isoforms/PTMs) across conditions.
- Immunohistochemistry (IHC): assess distribution across tissue compartments and compare staining patterns between groups.
- Immunofluorescence / ICC: evaluate subcellular localization and co-localization with compartment markers.
- Flow cytometry: quantify target-positive populations and compare shifts after stimulation or differentiation.
- Immunoprecipitation (IP/Co-IP): enrich the target to study binding partners and complex composition (conceptual).
Across these uses, researchers typically interpret changes in signal as relative differences between matched sample groups, considering sample preparation and biological context.
Notes for experimental interpretation
- Apparent molecular weight can vary due to isoforms, proteolysis, glycosylation, phosphorylation, and sample preparation differences.
- Species reactivity and epitope conservation can influence observed signal patterns, especially in cross-species studies.
- Control concepts: include appropriate negative controls (e.g., isotype controls where relevant) and, when feasible, genetic or orthogonal controls (KO/KD, peptide competition, or independent assays) to support interpretation.
For antibody reagents, monoclonal antibodies are often chosen for epitope consistency across lots, while polyclonals may recognize multiple epitopes and can show different background characteristics depending on context.
