TUBGCP4 (Tubulin Gamma Complex Component 4) is a key subunit of the γ-tubulin ring complex (γ-TuRC), a multi-protein assembly critical for microtubule nucleation and organization in eukaryotic cells. As part of the γ-TuRC, TUBGCP4 contributes to the formation of microtubule networks essential for cell division, intracellular transport, and maintenance of cell shape. The γ-TuRC anchors to centrosomes and other microtubule-organizing centers (MTOCs), where it templates the polymerization of α/β-tubulin dimers into microtubules. Antibodies targeting TUBGCP4 are widely used in research to study centrosome biology, mitotic spindle formation, and defects in microtubule dynamics linked to developmental disorders or cancers. These antibodies enable techniques like immunofluorescence, Western blotting, and immunoprecipitation to visualize TUBGCP4 localization, assess expression levels, or explore protein-protein interactions within the γ-TuRC. Dysregulation of TUBGCP4 has been implicated in microcephaly, ciliopathies, and tumorigenesis, making it a biomarker of interest in disease mechanisms. Commercial TUBGCP4 antibodies are typically validated for specificity against human or model organism antigens, with molecular weights around 100-110 kDa depending on post-translational modifications.
