Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: E. coli-derived human SAE2/UBA2 recombinant protein (Position: E449-K564). (reported region: E449-K564).
- Molecular weight context: reported MW: 90 kDa; calculated MW: 64133 MW
- Reactivity: Human,Mouse,Rat
- Applications: ELISA, Flow Cytometry, IF, IHC, IHC-F, ICC, WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
Heterogeneous nuclear ribonucleoprotein L; ubiquitin like modifier activating enzyme 2. Ubiquitin-like 1-activating enzyme E1B (UBLE1B) also known as SUMO-activating enzyme subunit 2 (SAE2) is an enzyme that in humans is encoded by the UBA2 gene. Posttranslational modification of proteins by the addition of the small protein SUMO (see SUMO1; MIM 601912), or sumoylation, regulates protein structure and intracellular localization. SAE1 (MIM 613294) and UBA2 form a heterodimer that functions as a SUMO-activating enzyme for the sumoylation of proteins Functional note: The heterodimer acts as an E1 ligase for SUMO1, SUMO2, SUMO3, and probably SUMO4. It mediates ATP-dependent activation of SUMO proteins followed by formation of a thioester bond between a SUMO protein and a conserved active site cysteine residue on UBA2/SAE2. Reported localization: Cytoplasm. Nucleus. Shuttles between the cytoplasm and the nucleus, sumoylation is required either for nuclear translocation or nuclear retention. Expression/tissue context: Duodenum, heart, lung and liver, but not thymus.
Research relevance and current trends
- Proteasome / Ubiquitin: Researchers commonly examine how UBA2 (Heterogeneous nuclear ribonucleoprotein L) relates to this theme using model systems and orthogonal readouts.
- Proteolysis/Ubiquitin: Researchers commonly examine how UBA2 (Heterogeneous nuclear ribonucleoprotein L) relates to this theme using model systems and orthogonal readouts.
Common research applications
- Western blotting: compare relative UBA2 (Heterogeneous nuclear ribonucleoprotein L) levels across conditions; band patterns may reflect isoforms and processing.
- IHC/IHC-F: assess spatial distribution of UBA2 (Heterogeneous nuclear ribonucleoprotein L) across tissue regions and cell types using matched controls.
- IF/ICC: evaluate subcellular localization and co-localization patterns; signal can depend on fixation/permeabilization and epitope accessibility.
- Flow cytometry: quantify target-positive populations and shifts in expression; gating strategy and background staining controls are essential.
- ELISA-compatible use: when applicable, interpret signal as relative abundance across sample sets with consistent handling and dilution strategy.
Notes for experimental interpretation
- Specificity notes: No cross reactivity with other proteins.
- Cross-reactivity: No cross-reactivity with other proteins.
- Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
- Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
