FAMILY

antioxidant family of proteins synthesized in the cytoplasm and functioning in mitochondria (ahpC/TSA family)

CATEGORY

enzyme , regulatory

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,organelle,mitochondria,matrix
	intracellular,cytoplasm,organelle,membrane
	intracellular,cytoplasm,organelle,endosome
	intracellular,cytoplasm,cytosolic
text	localized to the mitochondria (Moreira 2008)
	localized mainly to the photoreceptor inner segments, the outer and inner plexiform layers, and the ganglion cells (Moreira 2008)

basic FUNCTION	may be involved in the regulation of cellular proliferation, differentiation and antioxidant functions
	regulating erythroid differentiation (late stage of proerythrocyte differentiation)
	critical regulator of the abundance of mitochondrial H(2)O(2), which itself promotes apoptosis in cooperation with other mediators of apoptotic signaling
	may be important in protecting photoreceptor mitochondria especially in blue cones (Moreira 2008)
	PRDX3 and PRDX4, may act as new placental immune targets, and are involved in recurrent pregnancy loss
	mitochondrial peroxide reductase that regulates cellular redox state
	PRDX3 promotes hepatocellular carcinoma growth and mediates cell migration and invasiveness
	PRDX3 protected trophoblast cells against mitochondrial dysfunction and cellular senescence induced by oxidative stress
	involved in antioxidant defense and redox signaling
	PRDX3 protects against traumatic neuronal injury (TNI) insult by preserving mitochondrial function and mitochondrial biogenesis
	plays a major role in scavenging hydrogen peroxide of mitochondria
	plays an active role in the response to insulin release

INTERACTION

DNA

RNA

small molecule

protein	RPS6KC1-binding protein (interacts with PRDX3 through its pseudokinase domains, and with early endosomes through its PX domain)
	interacts with TXN2 and the TXN2/PRDX3 system functions in parallel with the GSX1 system to protect mitochondria from oxidative stress (Zhang 2007)
	interaction between TNNI3K and PRDX3 (Feng 2007)
