Serine 100-106 protein tyrosine kinase 2 beta Homo sapiens 49-65 10898514-6 2000 The down-regulation of cyclin D3 was at the level of translation, and this event was preceded by a pronounced inhibition of Akt/protein kinase B phosphorylation at Ser 473. Serine 164-167 protein tyrosine kinase 2 beta Homo sapiens 128-144 10722653-1 2000 The function of Akt (protein kinase B) is regulated by phosphorylation on two sites conserved within the AGC kinase family: the activation loop (Thr-308) in the kinase core and a hydrophobic phosphorylation site on the carboxyl terminus (Ser-473). Serine 238-241 protein tyrosine kinase 2 beta Homo sapiens 21-37 10601311-2 1999 Both of these kinases are activated in cells by phosphorylation of a conserved residue in the kinase domain (Thr-308 of protein kinase B (PKB) and Thr-252 of p70 S6 kinase) and another conserved residue located C-terminal to the kinase domain (Ser-473 of PKB and Thr-412 of p70 S6 kinase). Serine 244-247 protein tyrosine kinase 2 beta Homo sapiens 138-141 10567225-5 1999 In the present work, we have found that PKB directly phosphorylates mTOR and, using phosphospecific antibodies, we have shown this phosphorylation occurs at Ser(2448).

Serine 52-58 protein tyrosine kinase 2 beta Homo sapiens 66-82 10637513-2 1999 Full activation of protein kinase B requires 3-phosphoinositides and dual phosphorylation on threonine-308 and serine-473. Serine 111-117 protein tyrosine kinase 2 beta Homo sapiens 19-35 10637513-5 1999 Consistent with this, in a model COS cell system we show that expression of wild-type integrin-linked kinase promotes the wortmannin sensitive phosphorylation of serine-473 of protein kinase B and its downstream substrates, and inhibits C2-ceramide induced apoptosis.

Serine 95-98 protein tyrosine kinase 2 beta Homo sapiens 82-85 10497255-8 1999 In contrast, insulin-stimulated PKB-mediated phosphorylation of Ser residues within the phosphotyrosine binding/SAIN domain of IRS-1 protects IRS-1 from the rapid action of protein-tyrosine phosphatases and enables it to maintain its Tyr-phosphorylated active conformation. Serine 64-67 protein tyrosine kinase 2 beta Homo sapiens 32-35 7600304-4 1995 cDNA expression studies further revealed that this association is critical for the IL-2-induced activation of Syk PTK, which occurs primarily via the serine-rich region of the IL-2R beta chain, which is essential for proliferative signal transmission.
