This domain is found in 1,3-beta-glucan synthase component FKS1 from Saccharomyces cerevisiae and similar fungal proteins. FKS1 is involved in cell wall synthesis, maintenance and remodelling. This domain is predicted to adopt an all-alpha structure. It is often found C-terminal to Pfam:PF14288. Proteins with this domain also have Pfam:PF02364.	Domain

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].	Domain
