The table shows proteins with hydrophobic blocks of at least 14 amino acids, describes the structural nature of the run, and provides a reference to the structure in question. All long hydrophobic runs listed are parts of transmembrane helices, with the possible exception of the length 14 block of 1PF4, which was in a portion of sequence absent from the solved structure.
