ARF proteins

ARF proteins

coat-recruiting GTPases that function in the assembly of COPI coats at the endoplasmic reticulum-Golgi intermediate complex (ERGIC) and at the various surfaces of the Golgi complex, and in the assembly of clathrin coats at the trans-Golgi network.
See also: Golgi complex.
[ADP ribosylatin factor]

The 22 ARF proteins encoded by 22 ARF genes in Arabidopsis genome each contain a conserved DNA binding domain near their N terminus and most also have a dimerization domain near their C terminus that can interact with a corresponding domain in Aux/IAA proteins (Ulmasov et al.
Auxin probably activates ARF proteins by regulating turnover of ARF-interacting proteins called Aux/IAAs (Dharmasiri & Estelle, 2004).
We need to understand how the large families of AUX/IAA and ARF proteins regulate downstream gene expression.
