This model has been challenged by evidence showing that the glucocorticoid receptor (GR) forms tetramers upon ligand and DNA binding, which then drive receptor-mediated gene transactivation and transrepression. GR and the closely-related mineralocorticoid receptors (MR) interact to transduce corticosteroid hormone signaling, but whether they share the same quaternary arrangement is unknown. Here, we used a fluorescence imaging technique, Number &amp; Brightness, to study oligomerization in a cell system allowing real-time analysis of receptor-DNA interactions. Agonist-bound MR forms tetramers in the nucleoplasm and higher order oligomers upon binding to HREs. Antagonists form intermediate quaternary arrangements, suggesting that large oligomers are essential for function. Divergence between MR and GR quaternary structure is driven by different functionality of known and new multimerization interfaces, which does not preclude formation of heteromers. Thus, influencing oligomerization may be important to selectively modulate corticosteroid signaling.<\/jats:p>","DOI":"10.1101\/2023.01.26.525752","type":"posted-content","created":{"date-parts":[[2023,1,27]],"date-time":"2023-01-27T20:20:43Z","timestamp":1674850843000},"source":"Crossref","is-referenced-by-count":4,"title":["The mineralocorticoid receptor forms higher order oligomers upon DNA binding"],"prefix":"10.64898","author":[{"given":"Gregory","family":"Fettweis","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas A.","family":"Johnson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian","family":"Almeida-Prieto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4515-8058","authenticated-orcid":false,"given":"Diego M.","family":"Presman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gordon L.","family":"Hager","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4324-2793","authenticated-orcid":false,"given":"Diego Alvarez","family":"de la Rosa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"54368","reference":[{"key":"2023061612550707000_2023.01.26.525752v2.1","doi-asserted-by":"publisher","DOI":"10.1210\/en.2012-1210"},{"key":"2023061612550707000_2023.01.26.525752v2.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.bmc.2005.05.037"},{"key":"2023061612550707000_2023.01.26.525752v2.3","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M115.657957"},{"key":"2023061612550707000_2023.01.26.525752v2.4","doi-asserted-by":"publisher","DOI":"10.1126\/science.3037703"},{"key":"2023061612550707000_2023.01.26.525752v2.5","doi-asserted-by":"crossref","first-page":"17","DOI":"10.1016\/bs.vh.2018.10.009","article-title":"Evolution of the Mineralocorticoid Receptor","volume":"109","year":"2019","journal-title":"Vitam Horm"},{"key":"2023061612550707000_2023.01.26.525752v2.6","doi-asserted-by":"crossref","first-page":"1005","DOI":"10.1042\/CS20220212","article-title":"The non-steroidal mineralocorticoid receptor antagonist finerenone is a novel therapeutic option for patients with Type 2 diabetes and chronic kidney disease","volume":"136","year":"2022","journal-title":"Clin Sci (Lond)"},{"key":"2023061612550707000_2023.01.26.525752v2.7","doi-asserted-by":"publisher","DOI":"10.1210\/en.2014-1270"},{"key":"2023061612550707000_2023.01.26.525752v2.8","doi-asserted-by":"crossref","first-page":"3119","DOI":"10.1111\/bph.15708","article-title":"Mineralocorticoid receptor in cardiovascular diseases-Clinical trials and mechanistic insights","volume":"179","year":"2022","journal-title":"Br J Pharmacol"},{"key":"2023061612550707000_2023.01.26.525752v2.9","doi-asserted-by":"publisher","DOI":"10.1038\/s41419-018-0673-z"},{"key":"2023061612550707000_2023.01.26.525752v2.10","doi-asserted-by":"publisher","DOI":"10.1016\/S0092-8674(02)00817-6"},{"key":"2023061612550707000_2023.01.26.525752v2.11","doi-asserted-by":"publisher","DOI":"10.1126\/science.1123348"},{"key":"2023061612550707000_2023.01.26.525752v2.12","first-page":"e22709","article-title":"The mineralocorticoid receptor modulates timing and location of genomic binding by glucocorticoid receptor in response to synthetic glucocorticoids in keratinocytes","volume":"37","year":"2023","journal-title":"FASEB J"},{"key":"2023061612550707000_2023.01.26.525752v2.13","doi-asserted-by":"crossref","first-page":"2958","DOI":"10.1210\/en.2015-1008","article-title":"Aldosterone-Mediated Renal Sodium Transport Requires Intact Mineralocorticoid Receptor DNA-Binding in the Mouse","volume":"156","year":"2015","journal-title":"Endocrinology"},{"key":"2023061612550707000_2023.01.26.525752v2.14","doi-asserted-by":"crossref","first-page":"3107","DOI":"10.1016\/S0021-9258(18)49960-7","article-title":"Interaction of the glucocorticoid receptor DNA-binding domain with DNA as a dimer is mediated by a short segment of five amino acids","volume":"266","year":"1991","journal-title":"J Biol Chem"},{"key":"2023061612550707000_2023.01.26.525752v2.15","doi-asserted-by":"crossref","first-page":"363","DOI":"10.1038\/s41574-020-0349-5","article-title":"Nuclear receptor crosstalk -
