Immunofluorescence (IF): Localizes PIP4K2C in cellular compartments, such as autophagosomes or membranes, to study its role in vesicular trafficking and autophagy .
Western Blot (WB): Detects PIP4K2C at ~47–50 kDa in human kidney and brain tissues, validating knockout models or kinase inhibition studies .
ELISA: Quantifies PIP4K2C expression levels in serum or lysates for biomarker analysis .
While the FITC-conjugated antibody itself is a detection tool, studies using PIP4K2C-targeting reagents highlight its biological significance:
Immune Modulation: PIP4K2C knockout mice exhibit hyperactive immune responses and autoimmunity, suggesting its role in regulating mTORC1 signaling and immune tolerance .
Viral Infection: PIP4K2C binds SARS-CoV-2 nonstructural protein NSP6, impairing autophagic flux. Inhibitors like RMC-113 reverse this effect, demonstrating therapeutic potential .
Cancer Immunotherapy: Degradation of PIP4K2C enhances phagocytosis of tumor cells and synergizes with anti-PD-1 therapies in colorectal cancer models .
