DNAJB12 and DNAJB14 are transmembrane proteins in the endoplasmic reticulum (ER) that serve as co-chaperones for Hsc70/Hsp70 heat shock proteins. We demonstrate that over-expression of DNAJB12 or DNAJB14 causes the formation of elaborate membranous structures within cell nuclei. which we designate DJANGOS for DNAJ-associated nuclear globular structures. DJANGOS contain DNAJB12. https://fitnessgravesyardes.shop/product-category/arm-crank/
