The Section on Physical Biochemistry (SPB), Division of Intramural Research (DIR), Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH) in Bethesda, Maryland is recruiting a Postdoctoral Fellow with a background in cell biology, biochemistry or molecular biology. The SPB conducts basic and translational research of bone and extracellular matrix disorders. The DIR of NICHD seeks fundamental knowledge about the nature and behavior of living systems through basic, clinical, and population-based research. The DIR uses this knowledge to illuminate developmental origins of health and disease and to help ensure that women and men have good reproductive health, that children are born healthy, and that people develop to live productive lives. More detailed information about the NICHD DIR may be found at https://www.nichd.nih.gov/about/org/dir/Pages/index.aspx

The Postdoctoral Fellow will investigate molecular mechanisms of bone and lung pathology in osteogenesis imperfecta (OI) and related skeletal disorders, focusing on intracellular trafficking and degradation of the mutant molecules. Our lab discovered that folding, quality control and intracellular trafficking of type I procollagen is drastically different from most other secretory proteins. Misfolding of procollagen triple helix, which is responsible for over 80% of severe OI cases, is not detected by luminal chaperones in the Endoplasmic Reticulum (ER), resulting in noncanonical cell stress response. In particular, our recent multimodal transcriptomic analysis revealed upregulation of Atf5 and Hspa9 in osteoblasts instead of their Atf4 and Hspa5 paralogs that transduce the canonical unfolded protein response. However, the underlying molecular mechanisms remain unknown. The Postdoctoral Fellow will examine molecular pathways involved in this stress response and how misfolded procollagen activates it using cell culture and mouse models. Our group addresses these questions using multidisciplinary approaches, including biochemistry, biophysics, genetics, molecular and cellular biology, single cell and in situ RNA sequencing, and super resolution imaging of live cells. The lab is located in the Clinical Center, a highly interactive research environment within the main NIH campus.
