Outline of Final Research Achievements |
Mineralocorticoid receptor (MR) is involved in the development of hypertension and its detailed molecular mechanism has been focused. Evi-1 was identified as a candidate for novel MR-interacting protein through LC-MS/MS screening method. Evi-1 has SET domain, which includes histone methylation activity, in the whole molecule “Evi-1c”, but another isoform “Evi-1a”, which lacks SET domain, is supposed to act as dominant negative for Evi-1c. This study elucidated that Evi-1c functions as corepressor of MR but co-expression of Evi-1a suppresses the activity of Evi-1c. The recent GWAS results revealed that a certain SNP of Evi-1 gene is associated with hypertension or chronic kidney disease. It remains to be investigated whether this SNP might determine the ratio of Evi-1c/Evi-1a, leading to the change of MR sensitivity.
