Function
This antibody targets the phosphorylated form of microtubule-associated protein tau (MAPT) at Ser235. MAPT plays a crucial role in microtubule assembly and stability, potentially contributing to the establishment and maintenance of neuronal polarity. The C-terminus of MAPT binds to axonal microtubules, while the N-terminus binds to neural plasma membrane components, suggesting its function as a linker protein between these structures. Axonal polarity is predetermined by the localization of TAU/MAPT (within the neuronal cell) in the region of the cell body defined by the centrosome. The shorter isoforms of MAPT enable cytoskeletal plasticity, whereas the longer isoforms may primarily contribute to cytoskeletal stabilization.
