domain:The N-terminal coiled coil regions mediate homodimerization preferentially and heterodimerization type alpha/alpha. The C-terminal, non-coiled coil regions mediate heterodimerization type alpha/beta and interaction with PTPRD, PTPRF and PTPRS.,function:Alters PTPRF cellular localization and induces PTPRF clustering. 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.,similarity:Belongs to the liprin family. Liprin-alpha subfamily.,similarity:Contains 3 SAM (sterile alpha motif) domains.,subcellular location:Colocalizes with PTPRF at the cell surface.,subunit:Forms homodimers and heterodimers with liprins-alpha and liprins-beta. Interacts with the second PTPase domain of PTPRD, PTPRF and PTPRS.,tissue specificity:Expressed only in brain.,
Cytoplasm . Cell surface . Cell projection, dendritic spine . Colocalizes with PTPRF at the cell surface.
Expressed only in brain.
