Biological background
Biological context: Key component of the super elongation complex (SEC), a complex required to increase the catalytic rate of RNA polymerase II transcription by suppressing transient pausing by the polymerase at multiple sites along the DNA. In the SEC complex, AFF4 acts as a central scaffold that recruits other factors through interactions with ELL proteins (ELL, ELL2 or ELL3) and the P-TEFb complex. In case of infection by HIV-1 virus, the SEC complex is recruited by the viral Tat protein to stimulate viral gene expression. .
Expression and localization notes: cellular localization: Nucleus . Associates to transcriptionally active chromatin but not at snRNA genes. ., tissue context: Ubiquitously expressed. Strongly expressed in heart, placenta, skeletal muscle, pancreas and to a lower extent in brain. ..
Common research applications
- Western blotting (WB): Compare Hjurp levels across samples and conditions using appropriate loading and biological controls.
- Immunohistochemistry (IHC): Evaluate spatial distribution of Hjurp in tissue sections, considering fixation and antigen retrieval effects.
- Flow cytometry: Quantify Hjurp-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: Holliday junction recognition protein is a protein in humans that is encoded by the HJURP gene. HJURP (holliday junction recognition protein) is a protein coding gene. Diseases associated with HJURP include fibrillary astrocytoma. Among its related pathways are DNA damage and chromosome maintenance. Centromeric protein that plays a central role in the incorporation and maintenance of histone H3-like variant CENPA at centromeres. Acts as a specific chaperone for CENPA and is required for the incorporation of newly synthesized CENPA molecules into nucleosomes at replicated centromeres. Prevents CENPA-H4 tetramerization and prevents premature DNA binding by the CENPA-H4 tetramer. ly binds holliday junctions.
- Cross reactivity: No cross-reactivity with other proteins.
- Cellular localization: Nucleus . Associates to transcriptionally active chromatin but not at snRNA genes. .
- Tissue details: Ubiquitously expressed. Strongly expressed in heart, placenta, skeletal muscle, pancreas and to a lower extent in brain. .
