Promiscuous mismatch extension by human DNA polymerase lambda

Abstract excerpt

DNA polymerase lambda (Pol lambda) is one of several DNA polymerases suggested to participate in base excision repair (BER), in repair of broken DNA ends and in translesion synthesis. It has been proposed that the nature of the DNA intermediates partly determines which polymerase is used for a particular repair reaction. To test this hypothesis, here we examine the ability of human Pol lambda to extend mismatched...
