PPFIA3 (O75145) - Overview - Molecular Target Synopsis


PPFIA3, Liprin-alpha-3
UniProt O75145

Also Known as LIPA3_HUMAN, PPFIA3, KIAA0654

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. Forms homodimers and heterodimers with liprins-alpha and liprins-beta (PubMed:9624153). Interacts with the second PTPase domain of PTPRD, PTPRF and PTPRS (PubMed:9624153). Binds RIMS1, RIMS2, RIMS3 and RIMS4.
