Concentrative nucleoside transporter CNT3 (IPR030211)

Short name: CNT3

Family relationships

Description

Solute carrier family 28 member 3 (SLC28A3), also known as CNT3, is a sodium-dependent, pyrimidine- and purine-nucleoside transporter [PMID: 11032837, PMID: 16446384, PMID: 15738947]. The ability to substitute H+ for Na+ as one of the coupled cations during the substrate translocation cycle is a characteristic of CNT3 that distinguish it from CNT1 and CNT2 [PMID: 15870078]. It is the only mammalian H+-coupled concentrative nucleoside transporter identified so far, even though its prokaryotic orthologues, such as NupC, do actually transport nucleosides in an H+-dependent manner [PMID: 14668133].
