Protein attributes
| Sequence length | 1249 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Severs actin filaments and accelerates their polymerization and depolymerization By similarity. |
| Enzyme regulation | Phosphate inhibits both the depolymerization and severing activities. |
| Subunit structure | Interacts with actin at the FH2 domain By similarity. |
| Subcellular location | |
| Tissue specificity | Widely expressed. In the kidney, expression is apparent in podocytes and some tubule cells. Ref.16 |
| Domain | The WH2 domain acts as the DAD (diaphanous autoregulatory) domain and binds to actin monomers By similarity. Regulated by autoinhibition due to intramolecular GBD-DAD binding By similarity. The severing activity is dependent on covalent attachment of the FH2 domain to the C-terminus By similarity. |
| Involvement in disease | 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. Charcot-Marie-Tooth disease, dominant, intermediate type, 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. |
| Sequence similarities | Belongs to the formin homology family. Contains 1 FH2 (formin homology 2) domain. Contains 1 GBD/FH3 (Rho GTPase-binding/formin homology 3) domain. Contains 1 WH2 domain. |
| Sequence caution | The sequence AAH08756.2 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. The sequence AAH64828.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence ABD59343.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence ABD59344.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence ABD59345.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence BAB15224.1 differs from that shown. Reason: Erroneous termination at positions 636 and 759. Translated as Lys, Gln. The sequence EAW81872.1 differs from that shown. Reason: Erroneous gene model prediction. |
