The FIG4 antibody is a crucial tool in studying the FIG4 protein (also known as SAC3), a phosphoinositide phosphatase involved in intracellular signaling and membrane trafficking. FIG4 forms a complex with PIKFYVE kinase and VAC14 to regulate phosphatidylinositol-3.5-bisphosphate [PI(3.5)P2] levels, essential for lysosomal function, autophagy, and endosomal sorting. Mutations in the FIG4 gene are linked to neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS), hereditary spastic paraplegia, and Charcot-Marie-Tooth disease type 4J, highlighting its role in neuronal maintenance.
The FIG4 antibody is widely used in research to detect FIG4 expression and localization in tissues and cultured cells. It aids in elucidating mechanisms underlying FIG4-associated pathologies, such as lysosomal storage defects or impaired vesicle trafficking. Antibodies targeting specific epitopes (e.g., N-terminal, C-terminal, or Sac phosphatase domain) enable differentiation of wild-type versus truncated/mutated FIG4 in disease models. Applications include Western blotting, immunohistochemistry, and immunofluorescence to assess protein levels, subcellular distribution (e.g., endosomes, lysosomes), and interactions with binding partners. Commercial FIG4 antibodies are typically raised in rabbits or mice, validated for specificity across human, mouse, and rat samples. Their use has advanced understanding of FIG4’s role in cellular homeostasis and neurodegeneration, supporting therapeutic development for related disorders.
