Protein Structure

UniProt Annotation

Function

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). {ECO:0000250}.

Subcellular Localization

Cytoplasm {ECO:0000250}. Cell surface {ECO:0000250}. Note=Colocalizes with PTPRF at the cell surface. {ECO:0000250}.

Disease Associations

Tissue Specificity

Expressed only in the heart, brain, and skeletal muscle. {ECO:0000269PubMed:9624153}.
