WebMay 5, 1997 · The topogenic role of the hydrophobic signal domain was studied in vivo by expressing mutants of the asialoglycoprotein receptor subunit H1 in COS-7 cells. By replacing the 19-residue transmembrane segment of wild-type and mutant H1 by stretches of 7–25 leucine residues, we found that the length and hydrophobicity of the apolar … WebTo locate TV antenna broadcast transmitters and towers in your area on an easy to read map along with technical signal information, select your home state from the list of states …
