The protein kinase C (PKC) family includes isoforms such as PKC delta PKC mu/PKD PKC epsilon PKC beta 2 PKC gamma PKC zeta PKC eta PKC theta/PRKCQ PKC iota PKC nu/PRKD3 and CaMKII delta. These isoforms play roles in signal transduction and involve phosphorylation. Each isoform has a distinct mass; for example PKC delta weighs around 77 kDa. PKC isoforms express in various tissues like the brain immune cells and muscle. Some PKCs have specific tissues where they are mostly active which helps in their functional specificity.
Biological function summary
PKCs function as enzymes that regulate cell activities including proliferation differentiation and apoptosis. These activities occur through their second messenger-dependent activation. PKC isoforms often exist as part of larger protein complexes that determine substrate specificity and cellular localization. For instance PKC iota associates within a complex that facilitates its activity in the cytoplasm. The bisindolylmaleimide compounds act as inhibitors to PKC functions by blocking their phosphorylation activity.
Pathways
Multiple signaling cascades incorporate PKC isoforms. Among them the MAPK/ERK and PI3K/AKT pathways engage PKCs extensively. In the MAPK/ERK pathway PKCs phosphorylate components that activate ERK impacting cell cycle regulation. Additionally PKCs relate to proteins such as RAF and MEK within these pathways emphasizing their roles in transmitting extracellular signals to intracellular responses. In the PI3K/AKT pathway PKCs help in mediating cell survival signals contributing to their significance in cellular homeostasis.
PKC isoforms have associations with cancer and type II diabetes. For instance aberrant PKC epsilon activity links to cancer progression due to its role in controlling cell proliferation. Moreover altered PKC beta 2 activity impacts insulin signaling pathways contributing to insulin resistance observed in diabetes. These proteins when dysregulated serve as therapeutic targets and inhibitors like bisindolylmaleimide facilitate the exploration of therapeutic interventions for such conditions.
