PISD: Proteins and Enzymes

PISD, also referred to as Phosphatidylserine Decarboxylase proenzyme, is cleaved into two mature subunits called Phosphatidylserine decarboxylase alpha chain and Phosphatidylserine decarboxylase beta chain. The PISD proenzyme contains a LGST motif that is an autocatalytic cleavage site where it splits into the alpha chain and beta chain. PISD is part of the phosphatidylserine decarboxylase family and localizes to the mitochondrion. Current research on PISD is being conducted in relation to several diseases and disorders including carcinomas and malaria. Research has shown that PISD interacts with PMM2, SGPL1, DHX29, CRLS1 and NAPEPLD in pathways such as the FOXA1 transcription factor network, the metabolism of lipids and lipoproteins and glycerophospholipid metabolism.
