This antibody targets GA2OX3, an enzyme that catalyzes the 2β-hydroxylation of various biologically active gibberellins. This process is crucial for the homeostatic regulation of endogenous gibberellin levels. Gibberellin catabolism plays a central role in plant development. Specifically, GA2OX3 converts GA9/GA20 to GA51/GA29 and GA4/GA1 to GA34/GA8.
