Human BLASTP results (used to prepare the table)

Gene descriptions are from NCBI RefSeq. Search results were obtained with NCBI BLAST and RefSeq entries. When identical proteins are present, the self-match may not be listed first in BLASTP output. In such cases, the table above has been reordered to place it first.

See About the Figures for the scoring system used in the figure above right. The same scoring system was used in the table of BLASTP results.
