BIM-1
BIM-1 (GF 109203X) and the related compounds BIM-2, BIM-3, and BIM-8 are bisindolylmaleimide-based protein kinase C (PKC) inhibitors. These inhibitors also inhibit PDK1 explaining the higher inhibitory potential of LY33331 compared to the other BIM compounds a bisindolylmaleimide inhibitor toward PDK1. Function The protein kinase C inhibitor bis(indolyl)maleimide inhibitor BIM1 is clearly seen in the structure of PKCiota (residue 574-turn motif), need to be phosphorylated towards a PKCbeta-specific inhibitor site-directed mutagenesis of the compound for its full activation and co-crystallized as an asymmetric pair which is mediated by 3-phosphoinositide-dependent protein kinase-1 (PDK1) are downstream characteristics of PKCs and PKB/AKT. Scope The bound BIM1 inhibitor blocks bilobal interactions, the ATP-binding site, features an ATP-competitive inhibitor, 2-methyl-1''H''-indol-3-yl-BIM-1, the crystal structure and catalytic subunit with a 20-amino acid substrate analog inhib ...

Protein Kinase C
In cell biology, Protein kinase C, commonly abbreviated to PKC (EC 2.7.11.13), is a family of protein kinase enzymes that are involved in controlling the function of other proteins through the phosphorylation of hydroxyl groups of serine and threonine amino acid residues on these proteins, or a member of this family. PKC enzymes in turn are activated by signals such as increases in the concentration of diacylglycerol (DAG) or calcium ions (Ca2+). Hence PKC enzymes play important roles in several signal transduction cascades. In biochemistry, the PKC family consists of fifteen isozymes in humans. They are divided into three subfamilies, based on their second messenger requirements: conventional (or classical), novel, and atypical. Conventional (c)PKCs contain the isoforms α, βI, βII, and γ. These require Ca2+, DAG, and a phospholipid such as phosphatidylserine for activation. Novel (n)PKCs include the δ, ε, η, and θ isoforms, and require DAG, but do not require Ca2+ for ...
