Function
The small G-protein Rac or Ras-related C3 botulinum toxin substrate. Ras1 is involved in the regulation of cytoskeletal organization, cell adhesion, migration and morphological changes[1]. Ras3 binds to a variety of effector proteins to regulate cellular responses like cell spreading and the formation of actin-based protrusions.
Disease
Mutations in Rac2 are associated with neutrophil immunodeficiency syndrome.
Structural highlights
The interactions between Rac1 and YpkA are via switch I and switch II of Rac1 and a helical portion of the protein kinase YpkA[2]. GDP binding site on Rac1.
