Biological background

CTTN (protein: Glycogen synthase kinase-3 beta (gsk3b)) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Contributes to the organization of the actin cytoskeleton and cell shape (PubMed:21296879). Plays a role in the formation of lamellipodia and in cell migration. Plays a role in the regulation of neuron morphology, axon growth and formation of neuronal growth cones (By similarity). Through its interaction with CTTNBP2, involved in the regulation of neuronal spine density (By similarity). Plays a role in the invasiveness of cancer cells, and the formation of metastases (PubMed:16636290). Plays a role in focal adhesion assembly and turnover (By similarity). In complex with ABL1 and MYLK regulates cortical actin-based cytoskeletal rearrangement critical to sphingosine 1-phosphate (S1P)-mediated endothelial cell (EC) barrier enhancement (PubMed:20861316). Plays a role in intracellular protein transport and endocytosis, and in modulating the levels of potassium channels present at the cell membrane (PubMed:17959782). Plays a role in receptor-mediated endocytosis via clathrin-coated pits (By similarity). Required for stabilization of KCNH1 channels at the cell membrane (PubMed:23144454). . Reported cellular localization context: Cytoplasm, cytoskeleton . Cell projection, lamellipodium . Cell projection, ruffle. Cell projection, dendrite . Cell projection . Cell membrane ; Peripheral membrane protein ; Cytoplasmic side . Cell projection, podosome . Cell junction . Cell junction, focal adhesion . Membrane, clathrin-coated pit . Cell projection, dendritic spine . Cytoplasm, cell cortex . Colocalizes transiently with PTK2/FAK1 at focal adhesions (By similarity). Associated with membrane ruffles and lamellipodia. In the presence of CTTNBP2NL, colocalizes with stress fibers (By similarity). In the presence of CTTNBP2, localizes at the cell cortex (By similarity). In response to neuronal activation by glutamate, redistributes from dendritic spines to the dendritic shaft (By similarity). Colocalizes with DNM2 at the basis of filopodia in hippocampus neuron growth zones (By similarity). . Tissue expression notes (as provided): The alpha/alpha homodimer is expressed in embryo and in most adult tissues. The alpha/beta heterodimer and the beta/beta homodimer are found in striated muscle, and the alpha/gamma heterodimer and the gamma/gamma homodimer in neurons.

Research relevance and current trends

• Research context keywords from the source record include: Signal Transduction,Cytoskeleton,Cytoskeleton/ECM,Actin Assembly,Actin Binding Proteins,Actin, etc.,Microfilaments.
• 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.
• Flow cytometry: quantify target-positive populations and compare shifts in marker distributions.
• Immunoprecipitation (IP): enrich target complexes for downstream immunoblot or interaction analyses.

Workflow ideas (metafield): Validate CTTN antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect CTTN expression by Western blot in cell or tissue lysates, Detect CTTN in FFPE tissue sections by immunohistochemistry, Localize CTTN by immunofluorescence/immunocytochemistry in cultured cells, Quantify CTTN-positive cells by flow cytometry in single-cell suspensions, Enrich CTTN by immunoprecipitation from lysates for downstream analysis

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: 85 kDa; calculated MW: 61586 MW).
• Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
