Summary of the crystal structures of six mammalian membrane proteins
| Namea | Isolation | Number of Transmembrane Helices | Possible Functional Oligomerization |
|---|---|---|---|
| Bovine rhodopsin | Bovine rod photoreceptor outer segment | 7/monomer | Dimer |
| Rat Kv1.2K+ channel | Coexpressed with β subunit in yeast | 7/monomer | Tetramer |
| Bovine aquaporin 0 | Fresh bovine eye lens | 8/monomer | Tetramer |
| Rabbit Ca2+-ATPase | Rabbit hind leg muscle | 10/monomer | Monomer |
| Human LTC4S | Expressed in fission yeast | 4/monomer | Homotrimer |
| Human FLAP | Expressed in E. coli | 4/monomer | Homotrimer |
↵ a Structures were from the following: bovine rhodopsin from Palczewski et al. (2000), rat Kv1.2K+ channel from Long et al. (2005a), bovine aquaporin 0 from Harries et al. (2004), rabbit Ca2+-ATPase from Toyoshima and Mizutani (2004) and Toyoshima and Nomura (2002), human LTC4S from Molina et al. (2007), and human FLAP from Ferguson et al. (2007)
