Summary
PLSCR3 (phospholipid scramblase 3, HGNC:16495) is a protein-coding gene on chromosome 17p13.1, encoding Phospholipid scramblase 3 (Q9NRY6). Catalyzes calcium-induced ATP-independent rapid bidirectional and non-specific movement of the phospholipids (lipid scrambling or lipid flip-flop) between the inner and outer membrane of the mitochondria.
Enables calcium-dependent protein binding activity; metal ion binding activity; and phospholipid scramblase activity. Involved in several processes, including apoptotic process; mitochondrial membrane organization; and regulation of release of cytochrome c from mitochondria. Located in cytosol; mitochondrion; and plasma membrane.

Function. Catalyzes calcium-induced ATP-independent rapid bidirectional and non-specific movement of the phospholipids (lipid scrambling or lipid flip-flop) between the inner and outer membrane of the mitochondria. Plays an important role in mitochondrial respiratory function, morphology, and apoptotic response. Mediates the translocation of cardiolipin from the mitochondrial inner membrane to outer membrane enhancing t-Bid induced cytochrome c release and apoptosis. Enhances TNFSF10-induced apoptosis by regulating the distribution of cardiolipin in the mitochondrial membrane resulting in increased release of apoptogenic factors and consequent amplification of the activity of caspases. Regulates cardiolipin de novo biosynthesis and its resynthesis.
Subunit / interactions. Monomer. Forms homooligomers upon binding to Ca(2+), Pb(2+) and Hg(2+) ions. Interacts with PDCD6 in a calcium-dependent manner. Interacts with PRKCD; interaction is enhanced by UV irradiation.
Subcellular location. Mitochondrion membrane. Mitochondrion inner membrane. Nucleus.
Tissue specificity. Expressed in heart, placenta, lung, liver, skeletal muscle, kidney, pancreas, spleen, thymus, prostate, uterus, small intestine and peripheral blood lymphocytes. Not detected in testis, brain and liver.
Post-translational modifications. Phosphorylation at Thr-21 by PKC/PRKCD upon apoptotic stimuli enhances phospholipid scramblase activity. Palmitoylation regulates its localization to the cell membrane or the nucleus; trafficking to the cell membrane is dependent upon palmitoylation whereas in the absence of palmitoylation, localizes to the nucleus.
Activity regulation. Activated by Pb(2+) and Hg(2+) ions.
Domain organisation. The N-terminal proline-rich domain (PRD) is required for phospholipid scramblase activity.
Similarity. Belongs to the phospholipid scramblase family.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 48 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
