PI3-Kinases (PI3-Ks) are a family of lipid kinases that are implicated in signal transduction. PI3-K consists of two subunits; p85 and p10. The p85 subunit localize PI3-K activity to the plasma membrane while the p110 subunit contains the catalytic domain of PI3-K (1-2). Four isoforms of p110 has been found; alpha, beta, gamma, and the delta subunit (3). The gamma isoform is most clostly related to p110 alpha, and beta and has been shown not to interact with p85 in vivo (4). It has been found that in p110-gamma protein expression is lost in primary colorectal adeno-carcinomas and in colon cancer cell lines (5)
