Biochemical characterization of human DNA polymerase iota provides clues to its biological function.

abstract：:The PI3K (phosphoinositide 3-kinase) family of lipid kinases regulate cell motility in diverse organisms and cell types. In mammals, the main PI3K enzyme activated by chemokine receptor signalling is the class IB isoform, p110gamma. Studies of p110gamma-knockout mice have shown an essential function for this isoform i...
