InterPro domain: IPR044513

This entry represents a group of plant BTB/POZ and TAZ domain-containing proteins, including BT1-5 from Arabidopsis. They are scaffold proteins that play roles in both male and female gametophyte development [ 1 ]. BT2 can activate telomerase expression in mature Arabidopsis leaves [ 2 ]. It mediates multiple responses to nutrients, stresses, and hormones in Arabidopsis [ 3 ].
