Keyword - Transmembrane helix (KW-1133)
Protein with at least one transmembrane helical domain, a membrane-spanning domain with an hydrogen-bonded helical configuration, including alpha-, 3-10-, and pi-helices. The transmembrane alpha-helix is very common, while the 3-10-helix is found at the ends of alpha-helices and the pi-helix, is more rare.
