General description

Anti-Profilin 1 (N-terminal) is developed in rabbit using as immunogen a synthetic peptide corresponding to amino acid residues of human profilin 1, conjugated to keyhole limpet hemocyanin (KLH). Profilin 1 is a ubiquitous actin monomer-binding protein. Profilin 1 is highly expressed throughout development and adulthood in most of the tissues including brain.

Immunogen

synthetic peptide corresponding to amino acid residues 2-17 of human profilin 1, conjugated to KLH. The correspopnding rat and mouse sequence differs by one amino acid. This sequence is 70% similar to the corresponding sequence in profilin 2.

Application

Anti-Profilin 1 (N-terminal) antibody produced in rabbit has been used in immunoblotting and immunofluorescence.

Biochem/physiol Actions

Profilin 1 is involved in actin polymerization in response to extracellular signals. Profilins were shown to be important for normal cell proliferation, differentiation and motility.. Profilin 1 is a potent regulator of actin filament dynamics. Profilin 1 was suggested to act as a tumor suppressor protein based on its reduced expression in several types of invasive cancers and its ability to suppress tumorigenicity when overexpressed in breast cancer cells. Deletion of profilin 1 gene leads to an embryonic lethal phenotype and Miller-Dieker syndrome.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Single amino acid mutations in profilin 1 (PFN1) have been found to cause amyotrophic lateral sclerosis (ALS). Recently, we developed a mouse model for ALS using a PFN1 mutation (glycine 118 to valine, G118V), and we are now interested in

Profilin 1 is a crucial actin regulator, interacting with monomeric actin and several actin-binding proteins controlling actin polymerization. Recently, it has become evident that this profilin isoform associates with microtubules via formins and interferes with microtubule elongation at the cell
