This directory contains a single tab-separated value file mapping the
PomBase systematic identifiers to the associated gene names and gene products. 

This file is composed of 8 columns:
  - gene_systematic_id: PomBase systematic identifier (eg. SPAC1039.10)
  - gene_systematic_id_with_prefix: systematic ID with prefix (eg. PomBase:SPAC1039.10)
  - gene_name: main gene symbol (eg. mmf2)
  - chromosome_id: chromosome on which the gene is located (eg. chromosome_1)
  - gene_product: description of the gene product (eg. mitochondrial matrix protein, 
                  YjgF family protein Mmf2, reactive intermediate imine deaminase A homolog)
  - uniprot_id: UniProt accession number, for protein-coding genes only (eg. Q9UR06)
  - gene_type: PomBase feature type (eg. protein coding gene)
  - synonyms: other gene names used in the litterature (eg. hpm1,SPAC922.01)
