Nucleotide substitution: A423C. Nucleotides 295 through 819 from Pten sequence AF201905 were cloned in the forward and reverse directions into pJM1084 (the hairpin vector described in Reichhart et al. 2002 (FBrf0152370). The cloned sequences differed from AF201905 by an A to C change at nucleotide 423. Expression is governed by UAS regulatory sequences.
