WebThe Aux/IAA proteins regulate auxin-mediated gene expression by interacting with members of the AUXIN RESPONSE FACTOR protein family. Aux/IAA function is poorly understood; herein, we report the identification and characterization of insertion mutants in 12 of the 29 Aux/IAA family members. WebIAA is an apoptosis -inducing ligand in mammals. As of 2010, the signal transduction pathways are as follows: IAA/HRP activates p38 mitogen-activated protein kinases and c-Jun N-terminal kinases. It induces caspase-8 and caspase-9, which results in caspase-3 activation and poly (adp-ribose) polymerases cleavage.
