Protein Family Annotation Pfam Database Homepage

Chains Pfam Accession Pfam Identifier Pfam Description Type Source
D PF00071 Ras Ras family Domain Includes sub-families Ras, Rab, Rac, Ral, Ran, Rap Ypt1 and more. 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]. PFAM PF00071
A PF06456 Arfaptin Arfaptin-like domain Domain Arfaptin interacts with ARF1, a small GTPase involved in vesicle budding at the Golgi complex and immature secretory granules. The structure of arfaptin shows that upon binding to a small GTPase, arfaptin forms an elongated, crescent-shaped dimer of three-helix coiled-coils [1]. The N-terminal region of ICA69 is similar to arfaptin [2]. PFAM PF06456
