Here, we show that GLI3, a key SHH pathway [...]

JoVE: Paramagnetic Relaxation Enhancement for Detecting and Characterizing Self-Associations of Intrinsically Disordered Proteins (Libich Lab)

October 13, 2021

 Courtney N. Johnson1, David S. Libich1 Abstract Intrinsically disordered proteins and intrinsically disordered regions within proteins make up a large and functionally significant part of the human proteome. The highly flexible nature of these sequences allows them to form weak, long-range, and transient interactions with diverse biomolecular partners. Specific yet low-affinity interactions promote promiscuous binding [...]

Nature Communications: Structural basis of DNA synthesis opposite 8-oxoguanine by human PrimPol primase-polymerase (Gupta)

June 29, 2021

Olga Rechkoblit, Robert E. Johnson, Yogesh K. Gupta, Louise Prakash, Satya Prakash & Aneel K. Aggarwal Abstract PrimPol is a human DNA polymerase-primase that localizes to mitochondria and nucleus and bypasses the major oxidative lesion 7,8-dihydro-8-oxoguanine (oxoG) via translesion synthesis, in a mostly error-free manner. We present structures of PrimPol insertion complexes with a DNA template-primer and correct dCTP or erroneous […]

Pertsemlidis Lab Awarded American Lung Association Grant to Study “Identifying Exploitable Biomarkers of Lung Cancer Metastasis”

June 16, 2021

Abstract Rationale. Most cancer deaths are caused by metastatic disease, and the prevention of metastasis is a significant focus of clinical research. Aberrant expression of miRNAs has been found in all cancers, yielding insights into disease processes that would be difficult to detect by other methods and revealing fundamental therapeutic vulnerabilities. miRNAs have been shown […]
