BIOL 2021 Lecture Notes - Lecture 13: Ras Superfamily, Cytoskeleton
• Ras proteins (854-855)
o Activated by RTKs.
o Use adaptor proteins.
o Monomeric GTPases.
• Fig 15-8: monomeric GTPases
o Molecular switch.
o activate = GTP bound.
o Inactivate = GDP bound.
o GEF activates, GAP inactivates.
• Table 15-5 RAS superfamily
o Similar structures and mechanisms.
