Gene or accession: CG2094 DNA error at position 59361. Upstream nucleotides: aagttcgtcgcttccgcgct Substitution: base g should be a. Comments: Sequence for PTB (AF211191; AAF22979) is a cDNA that starts translation at a Met located 13 amino acids upstream of the init Met in Celera CG2094 (AE003780; AAF57208). There may be a sequencing error that is hiding this upstream possible initiating Met. thanks
