Summary

INF2 (inverted formin 2, HGNC:23791) is a protein-coding gene on chromosome 14q32.33, encoding Inverted formin-2 (Q27J81). Severs actin filaments and accelerates their polymerization and depolymerization.

This gene represents a member of the formin family of proteins. It is considered a diaphanous formin due to the presence of a diaphanous inhibitory domain located at the N-terminus of the encoded protein. Studies of a similar mouse protein indicate that the protein encoded by this locus may function in polymerization and depolymerization of actin filaments. Mutations at this locus have been associated with focal segmental glomerulosclerosis 5.

Function. Severs actin filaments and accelerates their polymerization and depolymerization.

Subunit / interactions. Interacts with actin at the FH2 domain. Interacts with DAAM2.

Subcellular location. Cytoplasm. Perinuclear region.

Tissue specificity. Widely expressed. In the kidney, expression is apparent in podocytes and some tubule cells.

Disease relevance. Focal segmental glomerulosclerosis 5 (FSGS5) [MIM:613237] A renal pathology defined by the presence of segmental sclerosis in glomeruli and resulting in proteinuria, reduced glomerular filtration rate and progressive decline in renal function. Renal insufficiency often progresses to end-stage renal disease, a highly morbid state requiring either dialysis therapy or kidney transplantation. The disease is caused by variants affecting the gene represented in this entry. Charcot-Marie-Tooth disease, dominant intermediate E (CMTDIE) [MIM:614455] A form of Charcot-Marie-Tooth disease, a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. The dominant intermediate type E is characterized by clinical and pathologic features intermediate between demyelinating and axonal peripheral neuropathies, and motor median nerve conduction velocities ranging from 25 to 45 m/sec. Patients additionally manifest focal segmental glomerulonephritis, proteinuria, progression to end-stage renal disease, and a characteristic histologic pattern on renal biopsy. The disease is caused by variants affecting the gene represented in this entry.

Activity regulation. Phosphate inhibits both the depolymerization and severing activities.

Domain organisation. The WH2 domain acts as the DAD (diaphanous autoregulatory) domain and binds to actin monomers. Regulated by autoinhibition due to intramolecular GBD-DAD binding. The severing activity is dependent on covalent attachment of the FH2 domain to the C-terminus.

Similarity. Belongs to the formin homology family.

Enriched among interaction partners

Reactome pathways and GO biological processes over-represented among this gene’s 111 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
