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 ^[2]. .
