One or more passes of polypeptide chains of the lipid bilayer, each consisting of about 25 hydrophobic residues with the occasional presence of a polar residue, anchor integral proteins in the cell membrane. These are known as transmembrane domains and participate in the functions of these proteins in some unspecified way. Encoded by a random exon make-up, sequences of these short stretches are highly variable with hardly any repetition.
