Background: Protein kinase C (PKC) is a family of serine-threonine kinases, which are classified into three major groups: classical (α, β and γ), novel (δ, ε, η, and θ) and atypical (μ, ξ and ι). Protein kinase C alpha (PKC alpha) is an ubiquitously expressed PKC isoform which is activated in response to many different kinds of stimuli causing translocation from the cytosol to specialized cellular compartments. Therefore, PKC alpha has been implicated in a variety of cellular functions including proliferation, apoptosis, differentiation, motility, and inflammation which are modulated by dynamic interactions with cell-type specific factors, substrates, modulators and PKC anchoring proteins.
