Actin binding protein,ALS18,Epididymis tissue protein Li 184a,OTTHUMP00000125244,PFN 1,Pfn,PFN1,PROF1,Profilin I,Profilin-1,Profilin1,ProfilinI,This gene encodes a member of the profilin family of small actin-binding proteins. The encoded protein plays an important role in actin dynamics by regulating actin polymerization in response to extracellular signals. Deletion of this gene is associated with Miller-Dieker syndrome, and the encoded protein may also play a role in Huntington disease. Multiple pseudogenes of this gene are located on chromosome 1.
