| STX12 antibody detects Syntaxin 12, encoded by the STX12 gene on chromosome 1p34.1. STX12 antibody is widely used in studies of intracellular trafficking, endosomal sorting, and vesicular transport. Syntaxin 12 belongs to the SNARE (soluble NSF attachment protein receptor) family of proteins, which mediate membrane fusion events in the endocytic and exocytic pathways. Specifically, Syntaxin 12 localizes to early and recycling endosomes, where it contributes to sorting and trafficking of receptors and other cargo between endosomes and the plasma membrane.Structurally, Syntaxin 12 is a ~34 kDa protein with a typical SNARE domain that forms alpha-helical coiled-coils with other SNAREs. This domain interacts with SNAP and VAMP proteins to form ternary SNARE complexes required for vesicle fusion. A transmembrane helix anchors Syntaxin 12 to endosomal membranes, while its N-terminal regulatory domain mediates interactions with tethering factors and regulatory proteins.Functionally, STX12 coordinates recycling of important receptors, including transferrin receptor, integrins, and immune receptors. By regulating receptor trafficking, it influences nutrient uptake, adhesion, migration, and signaling. STX12 also contributes to immune function by regulating recycling of MHC class II and T-cell receptors. Knockdown experiments demonstrate that loss of STX12 disrupts receptor recycling, leading to impaired signaling and defective cell migration. Researchers employ STX12 antibody to investigate membrane trafficking, endosome dynamics, and immune signaling pathways.Clinically, Syntaxin 12 has been implicated in neurological disorders, immunity, and cancer. Altered trafficking through STX12-associated pathways may contribute to neurodegenerative disease, where endosomal dysfunction is a hallmark. Its role in immune receptor recycling suggests relevance in autoimmune disease and immunodeficiency. In cancer, STX12 expression correlates with migration and invasion potential of tumor cells, linking trafficking machinery to malignancy. NSJ Bioreagents offers STX12 antibody to support cell biology, immunology, and cancer research.Experimentally, STX12 antibody is used in western blotting to detect the ~34 kDa protein, in immunofluorescence microscopy to visualize endosomal localization, and in immunohistochemistry to study tissue-specific expression. Co-immunoprecipitation with STX12 antibody helps identify interacting SNARE partners and regulators of endosomal sorting. |
