Gene : RGP1 A. thaliana

DB identifier  ? AT3G02230 Secondary Identifier  ? locus:2076482
Name  ? reversibly glycosylated polypeptide 1 Brief Description  reversibly glycosylated polypeptide 1
TAIR Computational Description  reversibly glycosylated polypeptide 1;(source:Araport11)
TAIR Curator Summary  RGP1 is a UDP-arabinose mutase that catalyzes the interconversion between the pyranose and furanose forms of UDP-L-arabinose. It appears to be required for proper cell wall formation. rgp1/rgp2 (at5g15650) double mutants have a male gametophyte lethal phenotype. RGP1 fusion proteins can be found in the cytosol and peripherally associated with the Golgi apparatus. The mRNA is cell-to-cell mobile.
TAIR Short Description  reversibly glycosylated polypeptide 1

Type Comment Proteins
RGP1_ARATH function UDP-L-arabinose mutase involved in the biosynthesis of cell wall non-cellulosic polysaccharides. Catalyzes the interconvertion of UDP-L-arabinopyranose (UDP-Arap) and UDP-L-arabinofuranose (UDP-Araf) in vitro. Preferentially catalyzes the formation of UDP-Arap from UDP-Araf. At thermodynamic equilibrium in vitro the ratio of the pyranose form over the furanose form is 95:5. Is not active on other UDP-sugars (UDP-Gal, UDP-Xyl, UDP-Glc, GDP-Man and GDP-Fuc) (PubMed:21478444). Functions redundantly with RGP2 and is essential for proper cell walls and pollen development. Probably involved in the formation of the pectocellulosic cell wall layer intine. Is probably active as heteromer in vivo (PubMed:17071651).
RGP1_ARATH similarity Belongs to the RGP family.
RGP1_ARATH subcellular location Soluble and associated with peripheral membrane and endomembrane system.
RGP1_ARATH tissue specificity Predominantly expressed in shoot and root apical meristems. Expressed in epidermal cells of leaves, inflorescence stems and seed coat. Expressed in pollen.
