Description_x000D_ General description_x000D_ Monoclonal Anti-Profilin 1 (mouse IgG1 isotype) is derived from the hybridoma Profilin1-3 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a synthetic peptide corresponding to a sequence located near the C-terminus of human profiling 1, conjugated to keyhole limpet hemocyanin (KLH). Profilin-1 (Pfn1), a major actin-regulatory protein is mapped to human chromosome17p13. It is the most ubiquitous and abundant protein and is highly expressed throughout development and adulthood in most tissues including brain._x000D_ Immunogen_x000D_ synthetic peptide corresponding to a sequence located near the C-terminus of human profilin 1, conjugated to KLH.

Profilins were shown to be important for normal cell proliferation, differentiation and motility. Profilin 1 is a potent regulator of actin filament dynamics. It is 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 over expressed in breast cancer cells. Deletion of the profilin 1 gene leads to an embryonic lethal phenotype.
