We developed a robotic pipeline for high-throughput recombinant protein expression in C. elegans, expressing 10,167 open reading frames (ORFs). Protein hydrophobicity was identified as key for soluble protein production.

Area of Science:

  • Structural proteomics
  • Molecular biology
  • Biotechnology

Background:

  • Proteome-scale structural studies are vital for basic biology and therapeutic development.
  • Recombinant protein expression is critical for these structural proteomics initiatives.
  • Caenorhabditis elegans offers a high-quality genome sequence and ORFeome for such studies.

Purpose of the Study:

  • To develop and implement a robotic pipeline for high-throughput recombinant protein expression.
  • To investigate the feasibility of expressing the Caenorhabditis elegans ORFeome.
  • To identify factors influencing soluble protein expression.

Main Methods:

  • Utilized a robotic pipeline with Gateway cloning/expression technology and automated platforms.
  • Performed heterologous protein expression experiments on 10,167 C. elegans ORFs.

  • Employed bioinformatics analysis to determine factors affecting protein expression.

    • Main Results:

    • Successfully expressed recombinant proteins from 4854 out of 10,167 ORFs.
    • Achieved soluble expression for 1536 proteins.
    • Identified protein hydrophobicity as a significant predictor of soluble expression.

    Conclusions:

    • The developed robotic pipeline enables large-scale recombinant protein expression.
    • Protein hydrophobicity is a key determinant for achieving soluble protein products.
    • This high-throughput approach is adaptable for expressing proteins from other species.
