Involved in redox regulation of the cell. Acts as an antioxidant (By similarity). Expressed in kidney marrow. Widely expressed in all embryonic tissues from all stages. Expression is already detectable at the early stages from gastrula and somitogenesis, but within the embryonic tissues only; there is no expression within the nutrient cells of the yolk syncytial layer. Later in development, expression remains high and nonrestricted. The active site Cys-77 corresponds to one of the redox-active cysteines of peroxiredoxins. Belongs to the peroxiredoxin-like PRXL2 family. PRXL2A subfamily. Truncated C-terminus. Truncated C-terminus.
