Gene : ABCB19 A. thaliana

DB identifier  ? AT3G28860 Secondary Identifier  ? locus:2090734
Name  ? ATP-binding cassette B19 Brief Description  ATP binding cassette subfamily B19
TAIR Computational Description  ATP binding cassette subfamily B19;(source:Araport11)
TAIR Curator Summary  Encodes a member of the ATP-binding cassette (ABC) transporter family that is involved in auxin transport and is involved in postembryonic organ separation. Also known as AtMDR11 and PGP19. Possibly regulates auxin-dependent responses by influencing basipetal auxin transport in the root. Acts upstream of phyA in regulating hypocotyl elongation and gravitropic response. Exerts nonredundant, partially overlapping functions with the ABC transporter encoded by AtPGP1.

Type Comment Proteins
AB19B_ARATH developmental stage In seedlings, confined to hypocotyls in darkness, but expressed in all tissues except in hypocotyls in light. In flowers, present in all organs except petals.
AB19B_ARATH function Auxin efflux transporter that acts as a negative regulator of light signaling to promote hypocotyl elongation. Mediates the accumulation of chlorophyll and anthocyanin, as well as the expression of genes in response to light. Participates in auxin efflux and thus regulates the polar auxin basipetal transport (from auxin-producing leaves to auxin-sensitive tissues, and from root tips to root elongating zone). Involved in diverse auxin-mediated responses including gravitropism, phototropism and lateral root formation.
AB19B_ARATH similarity Belongs to the ABC transporter superfamily. ABCB family. Multidrug resistance exporter (TC 3.A.1.201) subfamily.
AB19B_ARATH tissue specificity Ubiquitous, mostly in shoot meristems.
