Rho proteins are a type of guanine nucleotide-binding protein. These proteins function as molecular switches within cells.
Rho Proteins: Molecular Switches
Rho proteins play a crucial role in cellular signaling pathways. They cycle between two states:
- Active State: Bound to GTP (guanosine triphosphate).
- Inactive State: Bound to GDP (guanosine diphosphate).
This cycling allows Rho proteins to regulate various cellular processes.
Function of Rho proteins
Rho proteins are involved in the control of:
- Actin cytoskeleton organization.
- Cell motility.
- Cell division.
- Gene transcription.
