  1. aSST = silk-specific transcript. See Methods for identification of SSTs.
  2. bPFAM ID was assigned using highest match to a domain with HMMer 3.0.
  3. cFruit fly, Drosophila melanogaster, proteins were from the reference sequences (RefSeq) available in NCBI as of July 2012.
  4. dFruit fly tissues with the highest FPKM support were selected from FlyBase FPKM report obtained April 2013.
  5. eInteraction partners are fruit fly genes noted in the FlyBase Physical Interaction Database obtained in April 2013 as interacting with the fruit fly homolog of black widow SSTs.
  6. fHomologous black widow UATs to fruit fly interaction partners were chosen by best BLASTX match (SSTs in parentheses).
