Structural and Mechanistic Studies of GlypicansPosted by: National Institutes of Health (NIH)
Posted date: 2019-Jun-28
The research group of Dr. Mitchell Ho at the National Cancer Institute (NCI) is seeking a postdoctoral fellow to conduct structural and functional studies on cell surface heparan sulfate proteoglycans, in particular glypicans. Our goal is to better understand the role of cell surface glypicans so we can develop more effective antibody-based cancer therapies (https://ccr.cancer.gov/Laboratory-of-Molecular-Biology/mitchell-ho). We are combining structural techniques such as macromolecular crystallography and cryo-EM with biochemical and molecular methods to investigate the structure and function of glypicans and their associated proteins including Wnt/Frizzled molecules. We have developed antibodies that can recognize the functional sites of glypicans (Feng et al. PNAS, 2013 PMID: 23471984; Gao et al. Hepatology 2014 PMID: 24492943; Gao et al. Nature Communications, 2015 PMID: 25758784) and used them as tools to study the structure and function of glypicans. We have been collaborating with both structural biologists and computational biologists to complement our studies.
For this position, we are looking for a candidate who will carry out both structural studies and biochemical experiments on glypicans (e.g. GPC3) that interact with Wnt/Frizzled molecules using nanobodies as tools. Here are our recent papers relevant to this project:
The candidates should hold a Ph.D. degree with a strong background in structural biology and biochemistry and have at least one first author publication in structural biology. Experience with molecular biology, protein expression, purification and biochemical characterization are required. Prior experience in any one or more of structural biology, membrane protein biochemistry, mammalian expression systems or computational modeling is highly desired.
It is absolutely essential that the candidate be highly motivated. The postdoctoral fellow will be working with colleagues and collaborators with diverse expertise in cancer biology and protein engineering.To Apply:
