This protein enables 9 target(s):
| Target | Category | Definition |
|---|---|---|
| organic anion transmembrane transporter activity | molecular function | Enables the transfer of organic anions from one side of a membrane to the other. Organic anions are atoms or small molecules with a negative charge which contain carbon in covalent linkage. [GOC:ai] |
| folic acid transmembrane transporter activity | molecular function | Enables the transfer of folic acid (pteroylglutamic acid) from one side of a membrane to the other. Folic acid is widely distributed as a member of the vitamin B complex and is essential for the synthesis of purine and pyrimidines. [GOC:ai] |
| folate:monoatomic anion antiporter activity | molecular function | Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: Folate derivative (out) + anion (in) = folate derivative (in) + anion (out). The Reduced Folate Carrier (RCF(SLC19A1) acts by an antiport mechanism. RCF carries several folate derivatives: MTX, PMX, ratitrexed, pralatrexate, 5-methyl THF, and 5-formyl THF. [GOC:mtg_transport, PMID:21568705, PMID:24745983, TC:2.A.48] |
| antiporter activity | molecular function | Enables the active transport of a solute across a membrane by a mechanism whereby two or more species are transported in opposite directions in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy. The reaction is: solute A(out) + solute B(in) = solute A(in) + solute B(out). [GOC:mtg_transport, ISBN:0815340729, PMID:10839820] |
| methotrexate transmembrane transporter activity | molecular function | Enables the transfer of methotrexate, 4-amino-10-methylformic acid from one side of a membrane to the other. Methotrexate is a folic acid analogue and a potent competitive inhibitor of dihydrofolate reductase. [GOC:ai] |
| xenobiotic transmembrane transporter activity | molecular function | Enables the directed movement of a xenobiotic from one side of a membrane to the other. A xenobiotic is a compound foreign to the organim exposed to it. It may be synthesized by another organism (like ampicilin) or it can be a synthetic chemical. [GOC:go_curators, GOC:krc] |
| 2',3'-cyclic GMP-AMP binding | molecular function | Binding to 2',3' cyclic GMP-AMP (cGAMP) nucleotide, a cyclic purine dinucleotide that consists of AMP and GMP units cyclized via 2',5' and 3',5' linkages. [GOC:dph, PMID:23258412, PMID:23910378] |
| cyclic-GMP-AMP transmembrane transporter activity | molecular function | Enables the transfer of cyclic-GMP-AMP from one side of a membrane to the other. [PMID:31126740] |
| folic acid binding | molecular function | Binding to folic acid, pteroylglutamic acid. Folic acid is widely distributed as a member of the vitamin B complex and is essential for the synthesis of purine and pyrimidines. [GOC:jl, ISBN:0198506732] |
