26296658 The data indicate that arfaptin 2 is the first molecule to regulate NF-kappaB signaling by interacting with the functional IkappaB kinase complex but not by direct inhibiting IKKbeta phosphorylation.
23695357 The binding of arfaptin1, but not arfaptin2, to PI(4)P is regulated by protein kinase D (PKD) mediated phosphorylation at Ser100 within the AH.
23638170 both Arf1 activation and high membrane curvature are required for efficient recruitment of Arfaptin2 to membranes
22679020 The Arl1.Arfaptin-2 BAR structure suggests that one of the two Arl1 molecules competes with Rac1, which binds to the concave face of the Arfaptin-2 BAR homodimer and may hinder its membrane association.
15809304 arfaptin 2 phosphorylation at Ser260 by Akt inhibits PolyQ-huntingtin-induced toxicity by rescuing proteasome impairment
11854752 arfaptin 2 is involved in regulating huntingtin protein aggregation
