Product Overview
This rabbit polyclonal antibody targets death-associated protein 1 (gene DAP) in human samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 11.2 kDa, and the supplier reports an observed band at about 15 kDa.
Death-associated protein 1 (DAP1) is a small, conserved proline-rich protein. It was first identified in screens for genes needed for interferon-γ-induced cell death, and has since been linked to repression of autophagy downstream of mTOR and, more recently, to ribosome hibernation, where it binds eIF5A near the ribosome exit tunnel to keep ribosomes inactive and stable.
