Urea active transporter (IPR031155)

Short name: DUR

Overlapping homologous superfamilies

Family relationships


This entry represents a group of urea transporters, including Dur3 from budding yeast and its homologues from plants. Budding yeast Dur3 is a plasma membrane transporter for both urea and polyamines [PMID: 8335627, PMID: 17218313]. In maize plants, ZmDUR3 functions as an active urea permease with physiological roles in effective urea uptake and nitrogen remobilisation [PMID: 25522795]. Arabidopsis AtDUR3 is the major transporter for high-affinity urea uptake in Arabidopsis roots [PMID: 17672841].
