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 (this entry), a Rab1-activation domain (Pfam:PF20851), and a C- terminal phosphatidylinositol 4-phosphate-binding (P4M) domain (Pfam:PF14860). The N-terminal is mostly alpha-helical, but also shows a short two-stranded beta-sheet [1,3].

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].

Shares P-loop motif with GTP_EFTU, arf and myosin_head. See Pfam:PF00009 Pfam:PF00025, Pfam:PF00063. As regards Rab GTPases, these are important regulators of vesicle formation, motility and fusion. They share a fold in common with all Ras GTPases: this is a six-stranded beta-sheet surrounded by five alpha-helices [1].
