PF14860DrrA phosphatidylinositol 4-phosphate binding domain (DrrA_P4M)DrrA phosphatidylinositol 4-phosphate binding domainThis domain binds to phosphatidylinositol 4-phosphate. It is found in Legionella pneumophila DrrA, a protein involved in the redirection of endoplasmic reticulum-derived vesicles to the Legionella-containing vacuoles [1,2]. Domain

SidM consi ...This domain is found in the type IV virulence effector SidM/DrrA from Legionella pneumophila. This protein has dual GEF and GDF activity specifically toward Rab1, a key regulator for endoplasmic reticulum (ER)-to-Golgi vesicle trafficking. SidM consists of an N-terminal helical domain, a Rab1-activation domain (this entry), and a C- terminal phosphatidylinositol 4-phosphate-binding (P4M) domain (Pfam:PF14860). The Rab1-activation domain strongly interacts with Rab1 switch regions leading to substantial conformational changes on SidM binding. This domain is organized into two layers of helices [1,3].
