WormWorks Parts List


All but one of the regulatory elements we isolated are promoters, and are described in brief detail below, with more elaborate information on their parts registry pages. The remaining BioBrick is the 3' UTR from unc-54, which is roughly equivalent to a bacterial terminator and performs a number of important regulatory functions in complement to the promoter. All complete C. elegans constructs must include some form of functional 3' UTR. Promoters were selected based on their utility, strength of expression, and ease of avoiding potentially harmful cutsites.


  • pGpd-2: gpd-2 is part of the glycolysis pathway. The gpd-2 promoter thus expresses at a very high level—AceView says 43.5 times the average for a C. elegans constitutive gene.
  • pHsp-3: HSP-3 is a protein involved in the heat shock response pathway, but it is expressed constitutively. AceView says this is 22.9 times the average.
  • pRab-7: rab-7 expresses a GTPase involved in endosome trafficking, and expresses at 4.3 times the average.


  • pSip-1: sip-1 encodes a member of the heat shock family of proteins. Accoring to AceView, sip-1 is expressed at a level 17.6 times the average, at all levels of development.


  • pMec-7:
  • pOdr-1:
