Gene : AT5G61670 A. thaliana

DB identifier  ? AT5G61670 Secondary Identifier  ? locus:2151556
Brief Description  orange protein
TAIR Computational Description  orange protein;(source:Araport11)
TAIR Curator Summary  Encodes a close homolog of the Cauliflower OR (Orange) protein that is located in the chloroplast of light grown organs but in the nucleus of etiolated cotyledons. The function of OR is to induce the differentiation of proplastids or other noncolored plastids into chromoplasts for carotenoid accumulation. Both proteins contain a Cysteine-rich zinc finger domain that is highly specific to DnaJ-like molecular chaperons. The AtOR protein interacts directly with the PSY (phytoene synthase) protein and acts as a positive posttranscriptional regulator of its expression, thereby affecting carotenoid biosynthesis.

Type Comment Proteins
ORANG_ARATH function Involved in chromoplast differentiation. Associated with a cellular process that triggers the differentiation of pro-plastids or other non-colored plastids into chromoplasts for carotenoid accumulation (PubMed:24267591). Is associated with carotenoid accumulation in chromoplasts (PubMed:26224804). Functions as a major regulator of the phytoene synthase PSY1 protein level and activity. Modulates carotenoid biosynthesis by means of post-transcriptional regulation of PSY1 (PubMed:25675505). Modulates carotenoid biosynthesis in part by up-regulating a series of endogenous carotenogenic genes (PubMed:25857664).
ORANG_ARATH similarity Belongs to the orange-like family.
ORANG_ARATH subcellular location Localizes in the nucleus in etiolated cotyledons.
