Protein Domain : Protein FAR-RED ELONGATED HYPOCOTYL 1 IPR037766

Type	Family
Description	This entry represents a group of plant proteins, including FHY1 (At2g37678) from Arabidopsis. Phytochrome A (phyA) is the photoreceptor in Arabidopsis that mediates the far-red light high radiance response. AtFHY1 is a key regulator of far red/red (FR/R) spectrum-specific responses by regulating phyA shuttling from the cytoplasm to the nucleus and by directly regulating the expression of some target genes. AtFHY1 phosphorylation is induced by the R signal, is part of the FR/R spectrum sensing mechanism that ensures its optimal response to specific light quality [ ]. AtFHY1 also has an independent role in gene modulation and plant development under far-red light [].This entry also includes FHL (FHY1 Like). FHL is essential for light-regulated PHYA nuclear accumulation and subsequent PHYA phototropic signaling processes [ , , ]. The transcription of FHY1 and FHL are controlled by FHY3 (Far-red elongated HYpocotyl 3) and FAR1 (FAr-red impaired Response 1), a related pair of transcription factors [].
