text: user3760: What is the difference between C383S and C383A? For C383S, does it mean Cysteine(C) position 383 in the sequence and its next amino acid connect to it is Serine(S)?
  
  user964: This means that at position 383 the Cysteine(C) is mutated to a Serine(S).  Depending on the organism and gene usually the mutation notation is linked to a specific transcript since the position could vary depending on transcript splicing.
