PROJECT   DESCRIPTION-  Heterotrimeric G proteins are signaling switches primarily activated by membrane receptors of the GPCR superfamily, the targets for >30% of FDA-approved drugs. However, we have recently discovered a GPCR-independent mechanism of heterotrimeric G protein activation that “rewires” this signaling pathway to regulate multiple cellular processes and diseases. Our research has direct implications in cancer cell biology, embryonic development and neurotransmission.

https://www.bumc.bu.edu/biochemistry/profiles/mikel-garcia-marcos/.

The primary project of the successful candidate will consist of characterizing and optimizing a newly identified small molecule inhibitor that blocks a GPCR-independent mechanism of G protein signaling and has anti-metastatic properties. This will involve biochemical analysis of compounds generated by chemist collaborators at our institution, and detailed studies on the cell biological consequences of the action of such compounds. Progressively, the potential anti-metastatic therapeutic activity of these compounds will also be investigated in mouse models.

In addition, it is also expected that the applicant will participate in related secondary projects and collaborative projects within and/or outside our laboratory.

QUALIFICATIONS REQUIRED- We are looking for candidates with a recent Ph.D. and experience in Cell Biology and Biochemistry, as demonstrated by a strong publication record. Prior knowledge of GPCR/G protein signal transduction is preferred but not essential. We are looking for motivated and creativeindividuals with a commitment to academic research who can work independently as well as in team-based projects. Good oral and written communication skill are a must.

The atmosphere in the laboratory is collaborative and multidisciplinary. The successful candidate will interact on a daily basis with colleagues carrying out studies on different areas of research (cancer, development, neurobiology) and approaches (purified proteins, structural biology, primary and cell line cultures, BRET, mice, frogs, etc). Our laboratory is highly committed to the career development of trainees.

The Department of Biochemistry at Boston University offers a highly collegial atmosphere and a first rate research environment.

TECHNICAL SKILLS- Experience with several of the techniques listed below is expected:

• Cellular and Molecular Biology: Cell culture, confocal and live cell fluorescence microscopy, molecular cloning, genetic manipulation of cell lines by CRISPR and RNAi, lentivirus production, etc

• Biochemistry: Protein purification, protein-protein interaction assays such as pulldowns and immunoprecipitations, immunoblotting, enzymatic assays, etc

• High-throughput assays: Fluorescence polarization, AlphaScreen, etc 

• Mouse work: cancer xenograft models

Interested candidates should send a CV, cover letter and contact information for 3 references.
