Product Overview
This rabbit polyclonal antibody targets GRB10-interacting GYF protein 2 (gene GIGYF2) in human samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 150.1 kDa, and the supplier reports an observed band at about 180 kDa.
GIGYF2 is a scaffold protein that joins the cap-binding protein 4EHP (EIF4E2) to form a complex that blocks translation initiation on selected mRNAs. By also bringing in TTP and the helicase DDX6, it couples translational silencing with mRNA decay, and it helps limit translation of faulty messages on which ribosomes stall. It is studied in RNA regulation and neurobiology.
