The bacterial artificial chromosome (BAC) RP23-350E13 carrying the tyrosine hydroxylase gene is modified so that it expresses the EGFP/Rpl10a fusion gene (containing an SV40-polyA stop) from the Th transcriptional start site. Ascl2 is present on BAC RP23-350E13. No information about possible expression of this gene is available. (J:101977)
