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 SH3KBP1 levels across samples and conditions using appropriate loading and biological controls.
- Immunohistochemistry (IHC): Evaluate spatial distribution of SH3KBP1 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 SH3KBP1-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: SH3 domain-containing kinase-binding protein 1 is an adaptor protein that in humans is encoded by the SH3KBP1 gene. This gene encodes an adapter protein that contains one or more N-terminal Src homology domains, a proline rich region and a C-terminal coiled-coil domain. The encoded protein facilitates protein-protein interactions and has been implicated in numerous cellular processes including apoptosis, cytoskeletal rearrangement, cell adhesion and in the regulation of clathrin-dependent endocytosis. Alternate splicing results in multiple transcript variants encoding distinct isoforms.
- Cross reactivity: No cross-reactivity with other proteins.
- Cellular localization: Cytoplasm. Nucleus. Nucleus. Cytoplasm.
- Tissue details: 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.
