Profilin-1 is a protein that in humans is encoded by the PFN1 gene.[1][2]


The protein encoded by this gene is a ubiquitous actin monomer-binding protein belonging to the profilin family. It is thought to regulate actin polymerization in response to extracellular signals. Deletion of this gene is associated with Miller-Dieker syndrome.[3]
