Updated: 2 months ago
Job Type: FullTime
Deadline: 10 Sep 2021

A 3-year postdoc position in protein engineering and biochemistry is available in the Ubiquitin Signalling and Inflammation Laboratory led by Associate Professor Rune Busk Damgaard from 1 November 2021 or shortly thereafter.

In the Ubiquitin Signalling and Inflammation Laboratory at The Technical University of Denmark (DTU), our mission is to unravel fundamental biological concepts and identify druggable signalling mechanisms in cell stress signalling to advance therapy for patients suffering from diseases caused by dysregulation of signalling homeostasis. More specifically, we aim to understand how ubiquitin modifications regulate cell signalling at the interface of cell stress responses, cell death, and metabolism, and how dysregulation of these signalling mechanisms promotes the development of diseases such as autoinflammatory conditions and cancer. The lab uses a mix of molecular cell biology, biochemistry, and -omics technologies to investigate and understand how the enigmatic 'atypical' ubiquitin chains (K6-, K11-, K27-, K29-, K33- and M1-linked chains) control cellular signalling and functions.

Ubiquitin modifications control a wide variety of signalling pathways, particularly related to cell stress and inflammation. When dysregulated, ubiquitin signalling contributes to development of chronic immune disorders and cancer. This project is part of the lab's major long-term strategy to identify ubiquitin-dependent signalling mechanisms that can be targeted pharmacologically to treat diseases related to chronic inflammatory or cell stress conditions.

Responsibilities and qualifications

The successful candidate is a protein engineer and biochemist with experience and a strong academic track-record in their field and who can work independently and develop their projects involving design, expression, and purification of recombinant constructs. The postdoc will spearhead the development of new affinity tools (e.g. single-domain antibodies and other protein binders) for exploring novel aspects of atypical ubiquitin chain signalling, including M1-linked/linear chains, to understand how these ubiquitin modifications control cell signalling. This will include production and engineering of ubiquitin-conjugating and deconjugating enzymes for assembly of polyubiquitin chains to be used for discovery of single-domain antibodies using phage display as well as developing protocols and strategies for the application of these affinity tools (single-domain antibodies) for analysis of cellular ubiquitin signalling.

The main tasks include:

  • To design and engineer recombinant proteins/antigens to be cloned and purified for in vitro assays and discovery single-domain antibodies
  • To develop new affinity reagents for atypical ubiquitin chains using our in-house phage display pipeline
  • To establish and apply assays to analyse atypical ubiquitin signalling mechanisms in vitro and during cells stress
  • To use the developed affinity reagents and protocols to elucidate new ubiquitin-dependent signalling mechanisms during cell stress
  • To disseminate and communicate the results through journal publications and conference attendance
  • To assist with laboratory management, student supervision, and funding applications

We are looking for a talented and curious candidate with the following qualifications and experience for this ambitious and pioneering project:

  • The candidate must hold a PhD degree (or equivalent) in protein science, biochemistry, molecular biology, or a related discipline (candidates that are nearing the completion of their PhD may apply)
  • The candidate should have a strong background in protein biochemistry, molecular biology, and experiment design
  • The candidate should be ambitious, driven, and have motivation to succeed within a competitive research field
  • The candidate should have experience with state-of-the-art protein / DNA construct design software and protein engineering
  • The candidate should have experience with recombinant protein expression and a broad range of analytical and preparative methods used within protein purification (e.g. FPLC systems such as ÄKTA, Bio-Rad NGC, or similar)
  • The candidate should demonstrate evidence of independent research capability and good problem-solving skills
  • The candidate should have a track record of publication with at least one first-author paper in internationally recognised, peer-reviewed journal
  • The candidate should have a demonstrated ability to collaborate with team members
  • The candidate should have excellent communication skills in English (written and spoken)

Experience with any of the following is highly desirable but not essential:

  • Demonstrated ability to attract funding
  • Demonstrated leadership and/or supervision skills
  • Experience with experimental biophysics (e.g. SPR, ITC, FIDA, fluorescence polarisation, etc.) and/or structural biology
  • Experience with analysis of cell signalling and multiprotein complexes (e.g. immunoprecipitation and pulldowns, western blotting, etc.)
  • Experience with phage display technologies and/or antibody discovery
  • Experience with ubiquitin signalling, protein quality control, or cell stress
  • Experience with mammalian cell culture and cell biology
  • Experience with mass spectrometry-based proteomics
