Background

S100A8 protein became the focus of intensive current research due to their association with numerous human disorders, including acute and chronic inflammatory conditions, autoimmune diseases, cancer, atherosclerosis, cardiomyopathies and neurodegenerative diseases, as well as due to their crucial roles in normal physiological processes within cells. S100A8 belongs to the family of low molecular weight S100 proteins (10–13 kDa) comprising 22 members to date and representing the largest subfamily of the EF-hand Ca2+-binding proteins. All S100 proteins share conserved structural motifs of two EF-hand Ca2+-binding domains connected by a variable hinge region that often confer biological activity. The tendency to form homodimers is common to all S100 proteins, including S100A8 and S100A9, with one exception—calbindin D9k is monomeric. Some members of the S100 protein family are also able to form heterodimers as observed f.e. for S100A8 and S100A9 or S100A1 and S100P, which suggests different functions for homo- and heterodimers.

Nice shoes!
Size: 11, Color: Black Full Grain
I bought them in black and I like them so much I will be buying the brown soon. They fit true to size and are comfortable and stylish. I like the clean simplicity. They're basically a dressy sneaker which is perfect for my job's 'dress code'. Yet they're stylish enough to be worn weekends or a night out. They seemed just a touch stiff out of the box but IMO that's completely normal and fine - after just a couple days of wearing them they are breaking in nicely. No complaints on that. They seem to be of very high quality and I'm very happy with them.
