Name
beta-2-microglobulin
About this Structure
This protein consists of seven Beta-sheets shown here in purple. It also has a small alpha-helix on the surface of the protein shown in teal. Notice also, the ligand, which allows for binding to occur. Beta-2-microglobulin is a serum protein found in association with the major histocompatibility complex (MHC) class I heavy chain on the surface of nearly all nucleated cells (Gussow et al., 1987 [PubMed 3312414])[1]
Here's a disulfide bond!!
There is a hydrophobic element to B2M. When all of the most hydrophobic residues are selected, it can be clearly seen that there is a Hydrophobic Core between the two Beta sheets. Speculation could say that it has evolved in this manner to protect the disulfide bond.
