     NCBI <URL:

     allows users to add functional annotation of genes by providing a
     PubMed identifier for the publication where the annotation was
     initially made and a concise phrase describing the function.
     hgu95av2GRIF maps probe identifiers to the PubMed identifiers for
     the publication reporting the functions of genes corresponding to
     the probe identifiers

_D_e_t_a_i_l_s:

     Probe ids are only mapped to the PubMed ids. Efforts are being
     made to also include the concise phrase describing the function of
     a gene.  

     Mappings were based on data provided by:
