Protein Domain : Protein indeterminate-domain 1-16 IPR031140

Type	Family
Description	This is a family of plant-specific transcription factors including protein indeterminate-domain 1-16 (IDD1-16) from Arabidopsis containing the conserved INDETERMINATE DOMAIN (IDD) with four zinc finger motifs. These proteins are involved in regulation of multiple developmental processes [ , ]. IDD8/NUC, IDD3/MAGPIE (MAG), and IDD10/JACKDAW (JKD) regulate root development and patterning [[, , ]. IDD8/NUTCRACKER (NUC) also regulates photoperiodic flowering by modulating sugar transport and metabolism []. IDD15/SHOOT GRAVITROPISM 5 (SGR5) is involved in the gravitropic response of inflorescence stems. INDETERMINATE1 plays an important role in regulating the transition to flowering in maize []. This family also includes similar proteins from rice, such as EHD2, which are transcription activators that act as a flowering master switches in both long and short days, independently of the circadian clock [, ].
Short Name	IDD1-16
