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.

So Much Easier Than Lotion Sunscreen
Size: 0.5 Ounce (Pack of 1)
I bought this mainly because getting regular sunscreen on my kid turns into a full argument every single time. This stick version made things way easier. I can swipe it on quickly without getting sunscreen all over my hands or in my child’s eyes. We used it outside for soccer practice and park days, and I liked how it stayed on even with sweating and running around. It also fits easily in my bag, so I keep taking it with us instead of forgetting sunscreen at home. Honestly one of those products I didn’t expect to care about this much, but now I’m glad I ordered it.

Easy to use
Size: 0.5 Ounce (Pack of 1)
This Banana Boat Sport Kids Sunscreen Stick is super easy to apply, especially for little hands. Provides good sun protection and the travel size is convenient. Would be perfect if it were a bit smoother on the skin, but overall very practical.

Such a great product that my child can apply it themselves and no more eyes burning
Size: 0.5 Ounce (Pack of 1)
I originally purchased this because I needed something that was about 5$ to make my order eligible for same day shipping. Well I'm so happy I ordered this because my 7 year old is doing swim lessons with school and this is the first sunscreen that she can actually apply by herself and doesn't burn her eyes or make her skin cold in the morning. We will be switching over to this now and I'll be purchasing another one for her for summer camp! It's so good that it doesn't have aerosol which they say is not good for us.

Works! No white face or red eyes!

This works well. Doesn’t leave your face white and doesn’t get into eyes. Perfect for kiddos in sports. Also great you can purchase with HSA.

So easy to use!
Size: 0.5 Ounce (Pack of 2)
Love this stuff! Found it at Walmart a few years ago and have been using since! Love the compact size for carrying around and so easy to get sunscreen on the face without getting it in the eyes! Keep one in the beach/pool bag and one in the “sports” bag for baseball.
