Functional context (as provided): Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. Reported cellular localization context: Nucleus. Chromosome. Tissue expression notes (as provided): Detected in the suprabasal layer of the stratified epithelium of the esophagus, exocervix, vagina, mouth and lingual mucosa, and in cells and cell clusters in the mucosa and serous gland ducts of the esophageal submucosa (at protein level). Expressed widely in the exocervix and esophageal epithelium, with lowest levels detected in the basal cell layer. .\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eResearch context keywords from the source record include: Cell Type Markers,Class I,Cytoskeleton,Cytoskeleton\/ECM,Intermediate Filaments,Microtubules,Signal Transduction,Tags \u0026amp; Cell Markers.\u003c\/li\u003e\n\u003cli\u003eCurrent studies often focus on connecting target abundance\/localization to pathway perturbations across models, tissues, and cell states.\u003c\/li\u003e\n\u003cli\u003eQuantitative and multiplexed assays (e.g., imaging + immunoblot panels) are commonly used to compare phenotypes across conditions and time-courses.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eWestern blotting (WB):\u003c\/strong\u003e assess relative target abundance across samples, treatments, or time-points.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry (IHC):\u003c\/strong\u003e evaluate spatial distribution of target-positive staining in tissue architecture.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunofluorescence\/ICC (IF\/ICC):\u003c\/strong\u003e visualize subcellular localization patterns and cell-to-cell heterogeneity.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eWorkflow ideas (metafield): Validate KRT4 antibody specificity using KO\/KD control samples (WB\/IF\/IHC as appropriate), Detect KRT4 expression by Western blot in cell or tissue lysates, Detect KRT4 in FFPE tissue sections by immunohistochemistry, Localize KRT4 by immunofluorescence\/immunocytochemistry in cultured cells\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eConsider isoforms and post-translational modifications (PTMs) that may shift apparent molecular weight or epitope accessibility.\u003c\/li\u003e\n\u003cli\u003eApparent molecular weight may vary by sample type and processing (observed MW: 47 kDa; calculated MW: 57285 MW).\u003c\/li\u003e\n\u003cli\u003eControl concepts: include appropriate negative controls (e.g., isotype, KO\/KD samples) and orthogonal validation when feasible.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eAdditional product details (from the source record)\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular weight (observed):\u003c\/strong\u003e 47 kDa\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCellular localization (provided):\u003c\/strong\u003e Nucleus.
