May regulate the disassembly of focal adhesions. May localize receptor-like tyrosine phosphatases type 2A at specific sites on the plasma membrane, possibly regulating their interaction with the extracellular environment and their association with substrates (By similarity).
Subcellular locations: Cytoplasm, Cell surface
Colocalizes with PTPRF at the cell surface.
Expressed only in the heart, brain, and skeletal muscle.
