Serine/threonine-protein kinase OSR1; Regulates downstream kinases in response to environmental stress. May also have a function in regulating the actin cytoskeleton; Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. STE20 subfamily (527 aa)

Solute carrier family 2, facilitated glucose transporter member 9; Transport urate and fructose. May have a role in the urate reabsorption by proximal tubules. Also transports glucose at low rate; Solute carriers (540 aa)

Solute carrier family 15 member 1; Proton-coupled intake of oligopeptides of 2 to 4 amino acids with a preference for dipeptides. May constitute a major route for the absorption of protein digestion end-products; Solute carriers (708 aa)

Sodium-dependent phosphate transport protein 4; Isoform 2- voltage-driven, multispecific, organic anion transporter able to transport para-aminohippurate (PAH), estrone sulfate, estradiol-17-beta-glucuronide, bumetanide, and ochratoxin A. Isoform 2 functions as urate efflux transporter on the apical side of renal proximal tubule and is likely to act as an exit path for organic anionic drugs as well as urate in vivo. May be involved in actively transporting phosphate into cells via Na(+) cotransport; Belongs to the major facilitator superfamily. Sodium/anion cotransporter family (498 aa)

Plasma alpha-L-fucosidase; Alpha-L-fucosidase is responsible for hydrolyzing the alpha-1,6-linked fucose joined to the reducing-end N- acetylglucosamine of the carbohydrate moieties of glycoproteins; Belongs to the glycosyl hydrolase 29 family (467 aa)

Folate transporter 1; Transporter for the intake of folate. Uptake of folate in human placental choriocarcinoma cells occurs by a novel mechanism called potocytosis which functionally couples three components, namely the folate receptor, the folate transporter, and a V-type H(+)-pump; Minor histocompatibility antigens (591 aa)

Sodium-dependent phosphate transport protein 1; Important for the resorption of phosphate by the kidney. May be involved in actively transporting phosphate into cells via Na(+) cotransport in the renal brush border membrane. Plays a role in urate transport in the kidney; Solute carriers (467 aa)

Multidrug and toxin extrusion protein 1; Solute transporter for tetraethylammonium (TEA), 1- methyl-4-phenylpyridinium (MPP), cimetidine, N-methylnicotinamide (NMN), metformin, creatinine, guanidine, procainamide, topotecan, estrone sulfate, acyclovir, ganciclovir and also the zwitterionic cephalosporin, cephalexin and cephradin. Seems to also play a role in the uptake of oxaliplatin (a new platinum anticancer agent). Able to transport paraquat (PQ or N,N-dimethyl-4-4’-bipiridinium); a widely used herbicid. Responsible for the secretion of cationic drugs across the brush border membranes (570 aa)
