Background

Calreticulin is a multifunctional protein. It acts as a main Ca(2+)-binding (storage) protein in the lumen of the endoplasmic reticulum. Calreticulin binds Ca2+ ions (a second messenger in signal transduction), rendering it inactive. The Ca2+ is bound with low affinity, but high capacity, and can be released on a signal. Located in storage compartments associated with the endoplasmic reticulum, calreticulin also binds to misfolded proteins and prevents them from being exported from the endoplasmic reticulum to the golgi apparatus. The amino terminus of calreticulin interacts with the DNA-binding domain of the glucocorticoid receptor and prevents the receptor from binding to its specific glucocorticoid response element. Calreticulin reduces the binding of androgen receptor to its hormone-responsive DNA element and inhibits androgen receptor and retinoic acid receptor transcriptional activities in vivo, as well as retinoic acid-induced neuronal differentiation. Therefore, calreticulin acts as a significant modulator of the regulation of gene transcription by nuclear hormone receptors.

Fit and comfort
Size: 12, Color: Ch British Tan/Ivory
These have to rate as equal to any shoes I've ever owned. I know everyone's foot is shaped differently but when I slipped my feet into these I was immediately sure I had made the correct choice. Sizing is true. You note, I'm sure, that these are slip-on shoes. My experience with slip-ons has been mixed as sometimes the heel tends to slip due to the maker leaving room for the slip-on function to take place. When I got these I discovered that the opening for my feet was so tight I needed to shoe-horn them in and it wasn't particularly easy. The heel counter was "high and tight" but once I got my feet in the shoes it was heaven. Then, after a couple of days wearing them I can now slip my feet into these slip-ons with ease and the shoes grip my feet like a lace-up shoe can do. I have one other pair of Cole Haans in the same size 12. They are also a wonderful fit for me. I highly recommend.

Great shoes true to size
Size: 11, Color: Ivory/Microchip/Ivory, Size: 11, Color: Ivory/Microchip/Ivory
Great shoes, came with box. Brand new, true to size 11 US ! :) in my country they cost 270 USD so, really nice and very comfortable shoe considering i have plantar fasciitis. 3 month update: They get wrinkles pretty fast in just a few weeks due to the material, it’s not noticeable to others at all, but it’s worth keeping this in mind when buying this particular model.
