InterPro domain: IPR014476

This entry includes AT-hook motif nuclear-localized proteins 15-29 (AHL15-29) from Arabidopsis [ 1 ]. They have two conserved structural units, the AT-hook motif and the Plant and Prokaryote Conserved (PPC) domain, the latter also known as DUF296. Members of the AHL family regulate diverse aspects of growth and development in plants [ 2 ]. AHL20 has been shown to negatively regulate defenses in Arabidopsis [ 2 ].
