Summary

Go to the top of the page Help

Official Symbol: HRB1
Official Full Name: Drought-responsive family protein
Primary source: TAIR:AT5G49230
Locus tag: AT5G49230
See related: Araport:AT5G49230
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: HYPERSENSITIVE TO RED AND BLUE; K21P3.11; K21P3_11
Summary: Identified in a screen for mutations hypersensitive to red and blue light. Mutants have shorter hypocotyls. Encodes a nuclear localized protein with similarity to drought induced proteins. Contains a ZZ zinc finger domain which is thought to mediate protein-protein interactions.May be involved in red and blue light signal transduction.

What's a GeneRIF?

We propose that a modification of HRB1 by PP7 under blue light is essential to acquire a proper conformation or to bring in new components for the assembly of a functional HRB1 protein complex
Title: Hypersensitive to red and blue 1 and its modification by protein phosphatase 7 are implicated in the control of Arabidopsis stomatal aperture.
HRB1 represents a signaling step that regulates FLOWERING LOCUS T (FT) expression downstream of red and blue light perception.
Title: HYPERSENSITIVE TO RED AND BLUE 1 and its C-terminal regulatory function control FLOWERING LOCUS T expression.
