Transmembrane Domain Biology
More broadly a transmembrane domain is any membrane spanning protein domain.
Transmembrane domain biology. Other domains characterize dna binding proteins. Transmembrane helices are visible in structures of membrane proteins determined by x ray diffraction they may also be predicted on the basis of hydrophobicity scales. They represent a segment of alpha helix of a transmembrane protein.
Amino acid stretches are called transmembrane domains. Since they are hydrophobic so they prefer to stay inserted inside the membrane of the cell. Transmembrane domains are regions of a protein that are hydrophobic so that they prefer to be inserted into the cell membrane such that the parts of the protein on either side of the domain are on opposite sides of the membrane.
Transmembrane domains tmds are the hydrophobic areas or regions of the proteins. A comprehensive reference 2008. Identification of transmembrane helices.
