Complex of N-terminal 6His-tagged recombinant, human p110α full length, containing the mutation H1047R, and untagged recombinant, human p85α full length. The H1047R substitution is a somatic mutation in p110α that has been associated with tumours of the colon, stomach, breast and brain. Combined in vitro and in vitro studies have shown that this mutation confers higher lipid kinase activity than wild type, and is able to induce oncogenic transformation.
