Arfaptin 1 is an ARF binding protein that inhibits PLD activation, vesicular trafficking and secretion.
In the present report, we show that arfaptin 1 interacts with 'high speed' membranes independently of ARF.
However, addition of myristoylated ARF3 (myrARF3) increases the association of arfaptin 1 with the membranes, suggesting that arfaptin 1 and ARF form a complex on the Golgi.
Utilizing several deletion mutants of arfaptin 1 it is shown that the association of arfaptin 1 with myrARF3 is mediated via two binding sites on arfaptin 1.
These two domains are needed for arfaptin 1 inhibition of PLD activation by myrARF3 in vitro.
