Biological background
Biological context: Catalytic histone acetyltransferase subunit of the RNA polymerase II elongator complex, which is a component of the RNA polymerase II (Pol II) holoenzyme and is involved in transcriptional elongation. Elongator may play a role in chromatin remodeling and is involved in acetylation of histones H3 and probably H4. Involved in acetylation of alpha-tubulin (PubMed:19185337). May also have a methyltransferase activity. Involved in cell migration. Involved in neurogenesis. Regulates the migration and branching of projection neurons in the developing cerebral cortex, through a process depending on alpha-tubulin acetylation.
Expression and localization notes: cellular localization: Cytoplasm. Nucleus. Nucleus. Cytoplasm., tissue context: Expressed at low levels in the more differentiated suprabasal regions of the small intestine, and at higher levels in the colon, mainly in the upper region and in scattered cells throughout the remaining epithelium. Also expressed in epithelial cells of bladder, ileum and stomach and at lower levels in pancreas and earskin. The phosphorylated form is nearly exclusively expressed in goblet cells of the small intestine and in the lumen-proximal cells of the colon (at protein level). Also expressed in jejunum and duodenum..
Common research applications
- Western blotting (WB): Compare ELP3 levels across samples and conditions using appropriate loading and biological controls.
- Immunohistochemistry (IHC): Evaluate spatial distribution of ELP3 in tissue sections, considering fixation and antigen retrieval effects.
- Flow cytometry: Quantify ELP3-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)
- Specificity: No cross reactivity with other proteins.
- Background: Elongator complex protein 3, also named KAT9, is a protein that in humans is encoded by the ELP3 gene. It is mapped to 8p21.1. ELP3 is the catalytic histone acetyltransferase subunit of the RNA polymerase II elongator complex, which is a component of the RNA polymerase II (Pol II) holoenzyme and is involved in transcriptional elongation. ELP3 supports the migration and branching of projection neurons through acetylation of alpha-tubulin in the developing cerebral cortex. In mammals, ELP3 is important for paternal DNA demethylation afterfertilization. ELP3 is potentially involved in cellular redox homeostasis by mediating the acetylation ofglucose-6-phosphate dehydrogenase. Besides, ELP3 may play a role in chromatin remodeling and is involved in acetylation of histones H3 and probably H4.
