Inverted formin-2 is a protein that in humans is encoded by the INF2 gene.^[1]^[2] It belongs to the protein family called the formins. It has two splice isoforms, CAAX which localizes to the endoplasmic reticulum and non-CAAX which localizes to focal adhesions and the cytoplasm with enrichment at the Golgi.^[3]^[4]^[5] INF2 plays a role in mitochondrial fission and dorsal stress fiber formation.^[5]^[6] INF2 accelerates actin nucleation and elongation by interacting with barbed ends (fast-growing ends) of actin filaments, but also accelerates disassembly of actin through encircling and severing filaments.^[7]

Clinical significance

It can be associated with Focal segmental glomerulosclerosis^[8] and Charcot-Marie Tooth Disease.^[9]
