1) All capital symbols denote human genes and gene products while lower case/italics symbols stand for rodent genes and gene products      (exception: OAT-K1 is a rat protein). To better discriminate between human, rat and mouse gene products sometimes a lower case h, r or m preceeds the abbreviation. However, this is not part of the gene or protein symbol.2) (h) human, (r) rat, (m) mouse
