Effects of missense mutations
WebA number of rare missense variants of the human β4 subunit have recently been linked to nicotine dependence and/or sporadic amyotrophic lateral sclerosis, and altered responses to nicotine have been reported for these variants; however, it is unknown whether the effects of mutations depend on the subunit within the ligand-binding couples and ...

Did you know?
A missense mutation is an alteration in the DNA sequence that results in a different amino acid being incorporated into the structure of a protein. Depending on which amino acid it codes for, missense mutationscan be conservative (i.e., the resulting protein is functional) or nonconservative (i.e., the resulting protein … See more A missense mutation is an alteration in the DNA that results in a different amino acid being incorporated into the structure of a protein. At a molecular level, DNA is made up of two strands of four nucleotides called adenine, cytosine, … See more Nonsense mutations replace an amino acid codon with an early stop codon, which prematurely signals the ribosome to stop building a protein.
