Biological background
Biological context: Plays a role in pre-mRNA splicing and 3'-end processing. By recruiting PRPF19 and the PRP19C/Prp19 complex/NTC/Nineteen complex to the RNA polymerase II C-terminal domain (CTD), and thereby pre-mRNA, may couple transcription to splicing. Induces cardiac troponin-T (TNNT2) pre-mRNA exon inclusion in muscle. Regulates the TNNT2 exon 5 inclusion through competition with MBNL1. Binds preferentially to a single-stranded structure within the polypyrimidine tract of TNNT2 intron 4 during spliceosome assembly. Required for the export of mRNA out of the nucleus, even if the mRNA is encoded by an intron-less gene. Represses the splicing of MAPT/Tau exon 10. Positively regulates pre-mRNA 3'-end processing by recruiting the CFIm complex to cleavage and polyadenylation signals.
Expression and localization notes: cellular localization: Nucleus., tissue context: Ubiquitous..
Common research applications
- Western blotting (WB): Compare GGA3 levels across samples and conditions using appropriate loading and biological controls.
- Immunohistochemistry (IHC): Evaluate spatial distribution of GGA3 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 GGA3-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: ADP-ribosylation factor-binding protein GGA3 is a protein that in humans is encoded by the GGA3 gene. This gene encodes a member of the Golgi-localized, gamma adaptin ear-containing, ARF-binding (GGA) family. This family includes ubiquitous coat proteins that regulate the trafficking of proteins between the trans-Golgi network and the lysosome. These proteins share an amino-terminal VHS domain which mediates sorting of the mannose 6-phosphate receptors at the trans-Golgi network. They also contain a carboxy-terminal region with homology to the ear domain of gamma-adaptins. Multiple alternatively spliced transcript variants have been identified in this gene.
- Cross reactivity: No cross-reactivity with other proteins.
- Cellular localization: Nucleus.
- Tissue details: Ubiquitous.
- Research category: ER Proteins,Golgi Proteins,Protein Trafficking,Signal Transduction
