Biological background
Biological context: Acts as negative regulator of T-cell receptor (TCR) signaling by dephosphorylation of the Src family kinases LCK and FYN, ITAMs of the TCRz/CD3 complex, as well as ZAP70, VAV, VCP and other key signaling molecules. Associates with and probably dephosphorylates CBL. Dephosphorylates LCK at its activating 'Tyr-394' residue. Dephosphorylates ZAP70 at its activating 'Tyr-493' residue. Dephosphorylates the immune system activator SKAP2. Positively regulates toll-like receptor (TLR)-induced type 1 interferon production. Promotes host antiviral responses mediated by type 1 interferon. Regulates NOD2-induced pro-inflammatory cytokine secretion and autophagy.
Expression and localization notes: cellular localization: Cytoplasm., tissue context: Spleen, thymus, lymph node and bone marrow..
Common research applications
- Western blotting (WB): Compare PTPN22 levels across samples and conditions using appropriate loading and biological controls.
- Immunohistochemistry (IHC): Evaluate spatial distribution of PTPN22 in tissue sections, considering fixation and antigen retrieval effects.
- Flow cytometry: Quantify PTPN22-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: Protein tyrosine phosphatase, non-receptor type 22 (lymphoid), also known as PTPN22, is a protein that in humans is encoded by the PTPN22 gene. It is mapped to 1p13.2. This gene encodes of member of the non-receptor class 4 subfamily of the protein-tyrosine phosphatase family. The encoded protein is a lymphoid-specific intracellular phosphatase that associates with the molecular adapter protein CBL and may be involved in regulating CBL function in the T-cell receptor signaling pathway. Mutations in this gene may be associated with a range of autoimmune disorders including Type 1 Diabetes, rheumatoid arthritis, systemic lupus erythematosus and Graves' disease. Alternatively spliced transcript variants encoding distinct isoforms have been described.
- Cross reactivity: No cross-reactivity with other proteins.
- Cellular localization: Cytoplasm.
- Tissue details: Spleen, thymus, lymph node and bone marrow.
- Research category: Protein Phosphorylation,Signal Transduction,Tyrosine Phosphatases
