RAB23
RAB23 is a member of the RAS oncogene family and is known to play a crucial role in the Sonic hedgehog signaling pathway, which is involved in the development and patterning of many body systems. It is also associated with Carpenter syndrome, a rare genetic disorder.
Function[edit | edit source]
RAB23 is a small GTPase, a type of enzyme that can hydrolyze guanosine triphosphate (GTP). It is involved in intracellular membrane trafficking, a process that transports proteins and lipids between different cellular compartments.
In the Sonic hedgehog signaling pathway, RAB23 acts as a negative regulator. This means it inhibits the pathway, preventing it from sending signals. This is important for controlling the development and growth of cells.
Clinical significance[edit | edit source]
Mutations in the RAB23 gene have been linked to Carpenter syndrome, a condition characterized by abnormalities of the skull, fingers and toes, obesity, and other health problems. The exact role of RAB23 in this syndrome is not fully understood, but it is thought to be related to its function in the Sonic hedgehog signaling pathway.
