Biological background
Biological context: Transcriptional activator that binds to the consensus sequence 5'-AGATAG-3' and plays a key role in cardiac development and function (PubMed:24000169, PubMed:27984724). In cooperation with TBX5, it binds to cardiac super-enhancers and promotes cardiomyocyte gene expression, while it downregulates endocardial and endothelial gene expression (PubMed:27984724). Involved in bone morphogenetic protein (BMP)-mediated induction of cardiac- specific gene expression. Binds to BMP response element (BMPRE) DNA sequences within cardiac activating regions (By similarity). Acts as a transcriptional activator of ANF in cooperation with NKX2-5 (By similarity). Promotes cardiac myocyte enlargement (PubMed:20081228). Required during testicular development (PubMed:21220346). May play a role in sphingolipid signaling by regulating the expression of sphingosine-1-phosphate degrading enzyme, spingosine-1-phosphate lyase (PubMed:15734735).
Expression and localization notes: cellular localization: Nucleus, tissue context: Widely expressed in hematopoietic cells. Expressed in neutrophils. Within the B-cell compartment, expressed from pro- and pre-B cells to plasma cells..
Common research applications
- Western blotting (WB): Compare GATA4 levels across samples and conditions using appropriate loading and biological controls.
- Immunohistochemistry (IHC): Evaluate spatial distribution of GATA4 in tissue sections, considering fixation and antigen retrieval effects.
- Flow cytometry: Quantify GATA4-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: Transcription factor GATA-4 is a protein that in humans is encoded by the GATA4 gene. This gene encodes a member of the GATA family of zinc-finger transcription factors. Members of this family recognize the GATA motif which is present in the promoters of many genes. This protein is thought to regulate genes involved in embryogenesis and in myocardial differentiation and function, and is necessary for normal testicular development. Mutations in this gene have been associated with cardiac septal defects. Additionally, alterations in gene expression have been associated with several cancer types.
- Cross reactivity: No cross-reactivity with other proteins
- Cellular localization: Nucleus
- Tissue details: Widely expressed in hematopoietic cells. Expressed in neutrophils. Within the B-cell compartment, expressed from pro- and pre-B cells to plasma cells.
