eIF-2 Kinase MeSH Descriptor Data 2026


MeSH Heading
eIF-2 Kinase
Tree Number(s)
D08.811.913.696.620.682.700.300
D12.776.476.563.300
Unique ID
D019892
RDF Unique Identifier
http://id.nlm.nih.gov/mesh/D019892
Scope Note
A dsRNA-activated cAMP-independent protein serine/threonine kinase that is induced by interferon. In the presence of dsRNA and ATP, the kinase autophosphorylates on several serine and threonine residues. The phosphorylated enzyme catalyzes the phosphorylation of the alpha subunit of EUKARYOTIC INITIATION FACTOR-2, leading to the inhibition of protein synthesis.
