\HeaderA{sysptmGN}{Map SysPTM protein identifier to Gene Name}{sysptmGN}
\begin{Description}\relax
sysptmGN maps SysPTM protein
identifier to the corresponding gene names.
\end{Description}
\begin{Details}\relax
Each protein identifier maps to a vector containing the gene
name or alias.

Mappings were based on data provided by: SysPTM (\url{http://www.biosino.org/papers/SysPTM/Current/ptm ; http://www.biosino.org/papers/SysPTM/Current/name ; http://www.biosino.org/papers/SysPTM/Current/Protein_ID_equal}) on

\end{Details}
\begin{Examples}
\begin{ExampleCode}
     # Convert to a list
     xx <- as.list(sysptmGN)
     # Remove protein that do not map to any GENENAME
     xx <- xx[!is.na(xx)]
     if(length(xx) > 0){
         # Gets the gene names for the first five probe identifiers
         xx[1:5]
         # Get the first one
         xx[[1]]
     }
\end{ExampleCode}
