Function
The small G-protein Rac or Ras-related C3 botulinum toxin substrate.
- Rac1 is involved in the regulation of cytoskeletal organization, cell adhesion, migration and morphological changes[1].
- Rac2 is expressed in hematopoietic cells exclusively[2].
- Rac3 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.
