WebNational Center for Biotechnology Information Autophosphorylation is a type of post-translational modification of proteins. It is generally defined as the phosphorylation of the kinase by itself. In eukaryotes, this process occurs by the addition of a phosphate group to serine, threonine or tyrosine residues within protein kinases, normally to regulate the catalytic activity. Autophosphorylation may occur when a kinases' own active site cataly… WebJan 15, 2006 · Autophosphorylation of the IGF-1 RTK and insulin RTK, respectively, was analyzed by a sandwich enzyme-linked immunosorbent assay (ELISA) essentially as described previously 22 using a tyrosine kinase assay kit (Sigma). Briefly, 96-well plates (Immunolon; Nunc, Roskilde, Denmark) were coated with 5 μg/well of the H-60 antibody … crowns in forge of empires
