Assistant Professor, Department of Genetics and BiochemistryVisit the Lackey Lab
I completed my B.S. and B.A. in Biochemistry and Chemistry at North Carolina State University in 2005. While at North Carolina State, I researched small nucleolar RNAs in Dr. E.S. Maxwell’s laboratory. After graduating, I joined Peace Corps South Africa and served as an Education Volunteer for three rural primary schools for two years. Upon returning to the USA, I attended graduate school at the University of Minnesota, Twin Cities, where I studied the APOBEC/AID family of cytosine deaminases and their role in viral restriction, cancer development and antibody maturation in Dr. Reuben Harris’s laboratory. I earned my Ph.D. in Molecular Biology from the U of M in 2012. I joined the laboratory of Dr. Alain Laederach at the University of North Carolina, Chapel Hill, where I learned experimental and computational methods for RNA structure modeling. I joined the Department of Genetics and Biochemistry faculty at Clemson University in 2020. My laboratory is housed at the Center for Human Genetics in Greenwood, SC.
RNA is a foundational molecule of molecular and cellular biology with a predisposition to form flexible structures that impact its regulation. My laboratory studies the structures RNA forms and their impact on processing of messenger RNAs (mRNAs). In alternative splicing, one pre-cursor mRNA has the potential to be spliced into multiple different mature mRNAs by recognizing alternative splice sites around the coding exons and removing different sections of introns. At the splice site, around the exon-intron junction, structured regions influence splice site recognition. A major question in my lab is how structured RNA elements and splicing proteins coordinate to regulate splicing across networks of mRNAs. In addition, many disease-associated variants occur in non-coding regions, such as introns, and may impact the structure and function of splicing elements. Identifying functional structures in pre-cursor mRNAs and variants that can alter their natural form and function is important for understanding alternative splicing and how it contribute to disease. We are also interested in how RNA structure plays a role in other post-transcriptional regulatory mechanisms, such as alternative polyadenylation and translational efficiency.
