PPFIA3: Proteins and Enzymes

PPFIA3, also known as Liprin-alpha-3, has a 1,194 amino acid long isoform that is 133kDa and a slightly shorter 1,185 amino acid isoform that is approximately 132kDa. PPFIA3 is a member of the LAR protein-tyrosine phosphatase-interacting protein (liprin) family. PPFIA3 is localized to the cytoplasm and cell surface, and is highly expressed in the brain. As a member of the Liprin family, research shows that PPFIA3 may play a role in the disassembly of focal adhesions. Current research surrounding PPFIA3 shows that it may be implicated in various diseases and disorders including cerebritis, cerebral malformations, cocaine abuse, neuronitis and epilepsy. PPFIA3 has also been shown to interact with GIT1, PTPRS, PIK3R1, ERC2, and PPFIBP2.
