The three-domain system is a biological classification introduced by Carl Woese in 1990 that emphasizes his separation of prokaryotes into two groups, originally called Eubacteria and Archaebacteria.

The transmembrane domain
In the majority of receptors for which structural evidence exists, transmembrane alpha helices make up most of the transmembrane domain.

Domains are a relatively new grouping. The three-domain system was first invented in 1990, but not generally accepted until later. Now, the majority of biologists accept the domain system, but a large minority use the five-kingdom method.

Domain
A discrete portion of a protein (and corresponding segment of gene) with its own function. The combination of domains in a single protein determines its overall function.

homeobox A 180 base pair, highly conserved DNA sequence encoding a protein domain (the homeodomain) found in many proteins that play a regulatory role in transcription. Particularly important in development.

Although some introns, such as those in globin genes, appear to be inserted at what are structural domain boundaries in the polypeptide, many intron insertion positions bear no relation to structural or functional domains.
