Fidgetin-Like Protein 2
- Molecular classification
- AAA+ ATPase, Microtubule-severing enzyme
01
Overview
Fidgetin-like 2 (FL2) is a microtubule-severing enzyme belonging to the AAA+ ATPase family. It plays a critical role in regulating the dynamics of the microtubule cytoskeleton, which is essential for various cellular processes including cell migration, axonal growth, and wound healing. FL2 acts as a negative regulator of cell migration and axon regeneration, making it a potential therapeutic target for enhancing tissue repair after injury and promoting nerve regeneration. Studies have also implicated FL2 in vascular and neuronal development.
