Vendor description (summary): Boster Bio Anti-Sprouty 4/Spry-4/SPRY4 Antibody Picoband® catalog # A04343-2.
Biological background
Biological context: Suppresses the insulin receptor and EGFR-transduced MAPK signaling pathway, but does not inhibit MAPK activation by a constitutively active mutant Ras. Probably impairs the formation of GTP-Ras. Inhibits Ras-independent, but not Ras-dependent, activation of RAF1.
Expression and localization notes: cellular localization: Ruffle membrane. Peripheral membrane protein. Cytoplasmic side. Cytoplasm., tissue context: Brain..
Common research applications
- Western blotting (WB): Compare SPRY4 levels across samples and conditions using appropriate loading and biological controls.
- Immunohistochemistry (IHC): Evaluate spatial distribution of SPRY4 in tissue sections, considering fixation and antigen retrieval effects.
- Flow cytometry: Quantify SPRY4-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 sprouty homolog 4 is a protein that in humans is encoded by the SPRY4 gene. It is mapped to 5q31.3. This gene encodes a member of a family of cysteine- and proline-rich proteins. The encoded protein is an inhibitor of the receptor-transduced mitogen-activated protein kinase (MAPK) signaling pathway. Activity of this protein impairs the formation of active GTP-RAS. Nucleotide variation in this gene has been associated with hypogonadotropic hypogonadism 17 with or without anosmia. Alternative splicing results in a multiple transcript variants.
- Cross reactivity: No cross-reactivity with other proteins.
- Cellular localization: Ruffle membrane. Peripheral membrane protein. Cytoplasmic side. Cytoplasm.
- Tissue details: Brain.
