9819411-3	1998	In this study, we have identified by using sequential deletion mutants of the rat cardiac alpha-MHC gene a 30-bp purine-rich negative regulatory (PNR) element located in the first intronic region that appeared to be essential for the tissue-specific expression of the alpha-MHC gene.	purine	113-119	myosin heavy chain 6	Homo sapiens	90-99	
12933792-0	2003	Single-stranded DNA-binding proteins PURalpha and PURbeta bind to a purine-rich negative regulatory element of the alpha-myosin heavy chain gene and control transcriptional and translational regulation of the gene expression.	purine	68-74	myosin heavy chain 6	Homo sapiens	115-139
