[[Category: | [https://www.uniprot.org/uniprot/DIOA3_DIOJA DIOA3_DIOJA] Storage protein of tuber. Involved in protection against oxidative stress (Probable). Has carbonate dehydratase, trypsin inhibitor, dehydroascorbate (DHA) reductase and monodehydroascorbate (MDA) reductase activities (PubMed:22195572). Catalyzes the reactions of carbonate dehydratase and DHA reductase independently of zinc and glutathione (GSH). The coupled reaction is capable of recycling a plant antioxidant ascorbate using ubiquitous compounds H(2)O and CO(2) (PubMed:25747844). Exhibits antioxidant activity. Able to scavenge 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. Exhibits immunomodulatory activity. Activates Toll-like receptor 4 signaling pathways by up-regulating the gene expression of pro-inflammatory cytokines, such as tumor necrosis factor alpha, interleukin-1 beta and interleukin-6, and chemokines RANTES and MCP-1, in mouse RAW 264.7 macrophages. Stimulates the phagocytosis of E.coli by the LPS-treated mouse macrophages (PubMed:22796748).<ref>PMID:22195572</ref> <ref>PMID:22796748</ref> <ref>PMID:25747844</ref> | ||
