Biological background
SPINK1 (protein: Glycogen synthase kinase-3 beta (gsk3b)) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Weakly binds calcium but binds zinc very tightly- distinct binding sites with different affinities exist for both ions on each monomer. Physiological concentrations of potassium ion antagonize the binding of both divalent cations, especially affecting high-affinity calcium-binding sites. Binds to and initiates the activation of STK38 by releasing autoinhibitory intramolecular interactions within the kinase. Interaction with AGER after myocardial infarction may play a role in myocyte apoptosis by activating ERK1/2 and p53/TP53 signaling. Could assist ATAD3A cytoplasmic processing, preventing aggregation and favoring mitochondrial localization. May mediate calcium-dependent regulation on many physiological processes by interacting with other proteins, such as TPR-containing proteins, and modulating their activity. . Reported cellular localization context: Cytoplasm . Nucleus . Tissue expression notes (as provided): Although predominant among the water-soluble brain proteins, S100 is also found in a variety of other tissues.
Research relevance and current trends
- Research context keywords from the source record include: Cell Biology,Cell Cycle,Cell Differentiation,Epigenetics and Nuclear Signaling,Neural Stem Cells,Stem Cells.
- Current studies often focus on connecting target abundance/localization to pathway perturbations across models, tissues, and cell states.
- Quantitative and multiplexed assays (e.g., imaging + immunoblot panels) are commonly used to compare phenotypes across conditions and time-courses.
Common research applications
- Western blotting (WB): assess relative target abundance across samples, treatments, or time-points.
- Immunohistochemistry (IHC): evaluate spatial distribution of target-positive staining in tissue architecture.
Workflow ideas (metafield): Validate SPINK1 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect SPINK1 expression by Western blot in cell or tissue lysates, Detect SPINK1 in FFPE tissue sections by immunohistochemistry
Notes for experimental interpretation
- Consider isoforms and post-translational modifications (PTMs) that may shift apparent molecular weight or epitope accessibility.
- Apparent molecular weight may vary by sample type and processing (observed MW: 11 kDa; calculated MW: 10713 MW).
- Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
