Bioss Inc.'s PGGT1A Polyclonal Antibody is a Rabbit Polyclonal antibody. This antibody has been shown to work in applications such as: Immunofluorescence, Immunohistochemistry, Immunohistochemistry - fixed, and Western Blot. The PGGT1A Polyclonal Antibody was generated using FNTA as the antigen and it reacts with Mouse.
Description
FNTA, also known as CAAX farnesyltransferase (FTase), attaches a farnesyl group from farnesyl pyrophosphate to cysteine residues at the fourth position from the C terminus of proteins that end in the so-called CAAX box, where C is cysteine, A is usually but not always an aliphatic amino acid, and X is typically methionine or serine. This type of posttranslational modification provides a mechanism for membrane localization of proteins that lack a transmembrane domain. This enzyme has the remarkable property of farnesylating peptides as short as four residues in length that conform to the CAAX consensus sequence. FNTA is also a specific cytoplasmic interactor of the transforming growth factor-beta and activin type I receptors. It is likely to be a key component of the signaling pathway which involves p21ras, an important substrate for farnesyltransferase
