RNA Structure and Regulation Group

RNA Structure and Regulation Group

Messenger RNAs (mRNAs) pass along information that can be decoded to produce protein. Importantly, these same mRNAs also contain information determining when, where and how much protein to make. This regulatory information is part of the RNA and can have a huge impact on the final protein output. The RNA Structure and Regulation group looks for ways to identify regulatory elements within mRNA and understand how regulatory elements function. Some examples of common regulatory elements are upstream open reading frames within the 5′ Untranslated Region (UTR) of a mRNA, splice sites at the junction between exons and introns and polyadenylation sites within the 3′ UTR. Local RNA structure can influence the activity of nearly all regulatory elements. We are also interested in how variation in our DNA impacts RNA regulation by altering RNA regulatory elements in mRNAs and disrupting protein expression. We are proud to be a part of the Center for Human Genetics and Department of Genetics and Biochemistry at Clemson University.

Lackey Lab Journal Club: miRNA neural network

Written by Baxton Munn 1/8/22 – miRNAs, aka micro RNAs, exist to silence genes at the mRNA level, eliciting their degradation through binding of their 3’-UTRs or repressing their translation. Previously, it has been reported that miRNAs play an important role in the brain, specifically the hippocampus, where deletion of Dicer, a protein key to …

Lackey Lab Journal Club: Branchpoints brought to you by CoLa-Seq

11/19/21 – In our pre-Thanksgiving journal club we discussed a bioRxiv paper from the Li and Staley laboratories at the University of Chicago. In this work, Zeng and co-authors describe CoLa-Seq (co- transcriptional lariat sequencing). CoLa-Seq is a new technique that detects lariat containing precursor RNAs and splicing by-products to identify branchpoints. The authors call …
