Biological background

FABP4 (protein: Glycogen synthase kinase-3 beta (gsk3b)) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Lipid transport protein in adipocytes. Binds both long chain fatty acids and retinoic acid. Delivers long-chain fatty acids and retinoic acid to their cognate receptors in the nucleus (By similarity). . Reported cellular localization context: Cytoplasm. Nucleus. Depending on the nature of the ligand, a conformation change exposes a nuclear localization motif and the protein is transported into the nucleus. Subject to constitutive nuclear export (By similarity). . Tissue expression notes (as provided): Most abundant in heart, brain, skeletal muscle and testis. Little expression observed in liver. .

• 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 FABP4 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect FABP4 expression by Western blot in cell or tissue lysates, Detect FABP4 in FFPE tissue sections by immunohistochemistry, Localize FABP4 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: 15 kDa; calculated MW: 14719 MW).
• Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
