Biological background
KRT5 (protein: T-cell surface glycoprotein CD4) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Plays a key role in the response to DNA damage. May have a role in checkpoint signaling during mitosis. Enhances TP53- mediated transcriptional activation. . Reported cellular localization context: Nucleus. Chromosome, centromere, kinetochore. Associated with kinetochores. Both nuclear and cytoplasmic in some cells. Recruited to sites of DNA damage, such as double stand breaks. H4K20me2 is required for efficient localization to double strand breaks and removal of proteins that have a high affinity for H4K20me2 such as L3MBTL1 and KDM4A is needed. Tissue expression notes (as provided): Released primarily from activated T lymphocytes.
Research relevance and current trends
- Research context keywords from the source record include: Class I,Cytoskeleton,Cytoskeleton/ECM,Intermediate Filaments,Signal Transduction.
- 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.
- Immunofluorescence/ICC (IF/ICC): visualize subcellular localization patterns and cell-to-cell heterogeneity.
Workflow ideas (metafield): Validate KRT5 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect KRT5 expression by Western blot in cell or tissue lysates, Detect KRT5 in FFPE tissue sections by immunohistochemistry, Localize KRT5 by immunofluorescence/immunocytochemistry in cultured cells
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: 62 kDa; calculated MW: 62378 MW).
- Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
