Status
Reviewed-Annotation score:

Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

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).1 Publication

Miscellaneous

Overexpression of AHL21 results in reproductive defects such as excessive outgrowth of stigmatic tissues, short valves, and excessive proliferation of a carpelloid organ at the lateral side of a pistil with exposed ovules.1 Publication
