Reference

J P Davies, Y A Ioannou. Dupilumab for the treatment of asthma. Topological analysis of Niemann-Pick C1 protein reveals that the membrane orientation of the putative sterol-sensing domain is identical to those of 3-hydroxy-3-methylglutaryl-CoA reductase and sterol regulatory element binding protein cleavage-activating protein.J Biol Chem. 2000 Aug 11;275(32):24367-74.

Background

The Niemann-Pick C1 (NPC1) protein is predicted to be a polytopic glycoprotein, and it contains a region with extensive homology to the sterol-sensing domains (SSD) of 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-R) and sterol regulatory element binding protein cleavage-activating protein (SCAP). To aid the functional characterization of NPC1, a model of NPC1 topology was evaluated by expression of epitope-tagged NPC1 proteins and investigation of epitope accessibility in selectively permeabilized cells. These results were further confirmed by expression of NPC1 and identification of glycosylated domains that are located in the lumen of the endoplasmic reticulum. Our data indicate that this glycoprotein contains 13 transmembrane domains, 3 large and 4 small luminal loops, 6 small cytoplasmic loops, and a cytoplasmic tail. Furthermore, our data show that the putative SSD of NPC1 is oriented in the same manner as those of HMG-R and SCAP, providing strong evidence that this domain is functionally important.

Bag not as described

Very cute bag, but not as described in picture. The bag I received is much smaller and does not come with additional coin purse. Disappointed.

Not the same bag
Size: One Size, Color: Dark Cappuccino, Size: One Size, Color: Dark Cappuccino
The item I received appears to be a smaller version of the bag without the small wallet that should be included. Do not buy it, and save yourself the trouble of having to return it.

Very Essential Pants!
Size: 0, Color: Mauve, Size: 0, Color: Mauve
I saw the mauve pants while browsing at a bargain price. I when I tried them on, I didn’t want to take them off. They looked great, fit perfectly and were so comfortable that I felt like I was wearing PJs. I ordered them in size 0. I am just shy of 5’ and thin, so finding casual but dressy slacks that fit is difficult. The material is soft and a perfect thickness to wear all year, not too heavy but provides enough warmth for cooler days. Being cotton with a tad of stretch keeps them from wrinkling a lot and looking fresh. In fact I loved them so much that I went back and bought every color available. Nice to not wear jeans dominate my choices. I took a picture showing all the colors which I bought. Oh, I love the style with the simple zipper in the front and welting on the legs. Also a feature is the fact that the waist hits my real waist and makes me look taller. Kudos on these VERY Essential pants.
