The Phospho-PKR/EIF2AK2-T446 Antibody (CABP1251) is a high-quality antibody developed for reliable detection and analysis of target proteins. PKR is known for its role in the cellular response to viral infection, stress, and inflammation, and its phosphorylation at T446 is critical for its activity in modulating translation and immune response.This highly specific antibody, raised in rabbits, is validated for use in Western blot applications and has been shown to be highly reactive with human samples. By targeting the phosphorylated form of PKR at T446, researchers can gain insights into the signaling pathways and regulatory mechanisms involving this protein, particularly in the context of viral infections, autoimmune disorders, and cancer.
This antibody is validated for use in WB, IF/ICC, ELISA applications and has demonstrated reactivity against Human, Mouse samples.

The protein encoded by this gene is a serine/threonine protein kinase that is activated by autophosphorylation after binding to dsRNA. The activated form of the encoded protein can phosphorylate translation initiation factor EIF2S1, which in turn inhibits protein synthesis. This protein is also activated by manganese ions and heparin. The encoded protein plays an important role in the innate immune response against multiple DNA and RNA viruses.
