AHL21

Gene
AHL21
Protein
AT-hook motif nuclear-localized protein 21
Organism
Arabidopsis thaliana
Length
285 amino acids
Function
Transcription factor that specifically binds AT-rich DNA sequences related to the nuclear matrix attachment regions (MARs). Binds to the MARs present in the ETTIN (ETT) promoter leading to a negative regulation of its gene expression. Functions as a molecular node downstream of the homeotic protein AGAMOUS (AG), regulating patterning and differentiation of reproductive organs. Acts as a chromatin remodeling factor that modifies the architecture of ETTIN (ETT) chromatin by modulating H3 methylation leading to the regulation of ETT expression. Seems to be involved in the regulation of a set of reproductives genes including CRABS CLAW (CRC), JAGGED (JAG) and KNUCKLES (KNU).
