Gene Information

human ... FMNL1(752)

General description

Formins contain a conserved formin homology 2 (FH2) domain that is essential for dimerization and subsequent actin filament assembly. N-terminal to this domain is the formin homology 1 (FH1) domain that functions in the physiological action of formins by recruiting profilin-bound actin monomers to the growing actin filament. FMNL1 contains a GTPase binding domain (GBD) and a diaphanous autoregulatory domain (DAD), additionally.

Anti-FMNL1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project ( Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting.

Biochem/physiol Actions

FMNL1 (formin-like 1) gene encodes a leukocyte formin that has been found to be overexpressed in lymphomas. FMNL1 is a member of the diaphanous-related formins (DRFs) that are activated by Rho GTPase binding to the GBD (GTPase binding domain). Formins are large multi-domain proteins that function in the polymerization of unbranched actin filaments and regulate cytoskeletal dynamics. They also function in the maintenance of cell polarity, adhesion and migration. The Rho GTPases, Rac1 and RhoA, are involved in the binding and activation of FMNL1.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.


Corresponding Antigen APREST70052.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide

Lipid droplets (LDs) are cellular organelles specialized in triacylglycerol (TG) storage undergoing homotypic clustering and fusion. In non-adipocytic cells with numerous LDs this is balanced by poorly understood droplet dissociation mechanisms. We identify non-muscle myosin IIa (NMIIa/MYH-9) and formin-like 1...
