Hsp70 promoter fragment and an AUG initiator codon drive expression of a 2.3kb Sh fragment including the last 40bp of exon 15 (including the 5' donor site), all of intron 15/16 (2.2kb) and the first 40bp of exon 16 (including the 3' acceptor site) fused to the Ecol\lacZ coding region.
Sh fragment encompassing the 5' splice site of exon 15 to the 3' splice site of exon 16 fused to the sequence encoding a lacZ reporter.
