Regulation of protein kinase B/Akt-serine 473 phosphorylation by integrin-linked kinase: critical roles for kinase activity and amino acids arginine 211 and serine 343.

Protein kinase B (PKB/Akt) is a regulator of cell survival and apoptosis. To become fully activated, PKB/Akt requires phosphorylation at two sites, threonine 308 and serine 473, in a phosphatidylinositol (PI) 3-kinase-dependent manner. The kinase responsible for phosphorylation of threonine 308 is the PI 3-kinase-dependent kinase-1 (PDK-1), whereas phosphorylation of serine 473 has been suggest...

Regulation of tumor angiogenesis by integrin-linked kinase (ILK).

We show that integrin-linked kinase (ILK) stimulates the expression of VEGF by stimulating HIF-1alpha protein expression in a PKB/Akt- and mTOR/FRAP-dependent manner. In human prostate cancer cells, knockdown of ILK expression with siRNA, or inhibition of ILK activity, results in significant inhibition of HIF-1alpha and VEGF expression. In endothelial cells, VEGF stimulates ILK activity, and in...

Integrin Linked Kinase (X-ILK) Function during Embryonic Development and within Adult Tissues of Xenopus laevis

Integrin linked kinase (ILK) is a serine/threonine protein kinase implicated in the phosphatidylinositol 3’kinase (PI3’K) pathway. Integrin linked kinase has been investigated in different organisms such as mammalian systems (human, mice, rat), insects (Drosophila) and nematodes (Cenorhabditis elegans), however to date little data regarding ILK research on amphibians has been reported. In...

Integrin-Linked Kinase Is a Functional Mn2+-Dependent Protein Kinase that Regulates Glycogen Synthase Kinase-3β (GSK-3β) Phosphorylation

BACKGROUND Integrin-linked kinase (ILK) is a highly evolutionarily conserved, multi-domain signaling protein that localizes to focal adhesions, myofilaments and centrosomes where it forms distinct multi-protein complexes to regulate cell adhesion, cell contraction, actin cytoskeletal organization and mitotic spindle assembly. Numerous studies have demonstrated that ILK can regulate the phosphor...

Negative regulation of TRPC3 channels by protein kinase C-mediated phosphorylation of serine 712.

TRPC3 is a nonselective cation channel member of the "canonical" transient receptor potential (TRPC) family whose members are activated by phospholipase C-coupled receptors. TRPC3 can be activated by the diacylglycerol analog 1-oleoyl-2-acetyl-sn-glycerol (OAG) in a protein kinase C-independent manner. On the other hand, phorbol 12-myristate 13-acetate (PMA) inhibits OAG-mediated TRPC3 channel ...
