Biological background

STX4 (protein: T-cell surface glycoprotein CD3 zeta chain) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Minus end-ed microtubule-dependent motor required for bipolar spindle formation (PubMed:15843429). May contribute to movement of early endocytic vesicles (By similarity). Regulates cilium formation and structure (By similarity). . Reported cellular localization context: Nucleus . Cytoplasm, cytoskeleton, microtubule organizing center, centrosome . Cytoplasm, cytoskeleton, spindle . Early endosome . Associated with nucleus during interphase, centrosomes in early and spindle in later mitosis. . Tissue expression notes (as provided): Most strongly expressed in skeletal and cardiac muscle. Also detected in smooth muscle. Weak expression in brain and lung.

Research relevance and current trends

• Research context keywords from the source record include: Cell Biology,Cell Cycle,Cell Division,Cytoskeleton,Cytoskeleton/ECM,Motor Proteins,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.

Workflow ideas (metafield): Validate STX4 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect STX4 expression by Western blot in cell or tissue lysates, Compare relative STX4 levels across experimental conditions (dose/time-course) using antibody-based readouts

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: 34 kDa; calculated MW: 73748 MW).
• Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
