General description

Mineralocorticoid receptor (UniProt P22199; also known as MR, Nuclear receptor subfamily 3 group C member 2) is encoded by the Nr3c2 (also known as MCR, Mlr) gene (Gene ID 25672) in rats. Mineralocorticoid receptor (MR) is expressed in multiple tissues, including renal epithelia, smooth muscle, endothelium, cardiomyocytes, and hippocampal neurons, where it mediates diverse functions. MR is activated by aldosterone and also by cortisol in cells that do not express 11β-hydroxysteroid dehydrogenase type 2 (11βHSD2). MR is normally activated by aldosterone, which is produced by adrenal glomerulosa in response to intravascular volume depletion and hyperkalemia. Consistently, gain of function mutations in MR lead to severe hypertension, often with hypokalemia, while loss of function mutations result in neonatal hypotension. Ser843 phosphorylation in the MR ligand-binding domain is reported to prevent MR ligand binding and activation. MR pS843 is found exclusively in intercalated cells of the distal nephrons in the kidney. Intravascular volume depletion, angiotensin II and WNK4 signaling reduce MR pS843 levels, whereas hyperkalemia increases MR pS843.

Characterization of Estrogen Receptor α Phosphorylation Sites in Breast Cancer Tissue Using the SNAP i.d® 2.0 System

A major focus of breast cancer research is to understand the mechanisms responsible for disease progression and drug resistance. Toward that end, it has been found that approximately two thirds of all human breast carcinomas overexpress the Estrogen Receptor α (ERα) protein and it remains the primary pharmacological target for endocrine therapy1,2. The normal cellular function of ERα is as a transcription factor that mediates a wide variety of physiological processes, many of which are dependent upon phosphorylation of the receptor at specific amino acid residues3,4. Indeed, ERα is known to be phosphorylated at a multitude of different sites, yet how these all correlate to disease remains unclear5. Here, we interrogated multiple sites of ERα for phosphorylation status by screening an extensive panel of different breast cancer patient samples and other non-breast cancer tissue microarray (TMA) slide samples to determine their relevance to disease.
