#3 - Generation Of Sult4a1 Gene Mutations In Sh-Sy5y Cells, Elisabeth Bradberry, Frank Crittenden

Georgia Undergraduate Research Conference (GURC)

The cytosolic sulfotransferases (SULT) are a superfamily of enzymes that catalyze the metabolism of various substrates throughout the body. One member, SULT4A1, has no known substrates and is highly conserved among all vertebrates which is not a shared characteristic among the SULT family. Also unique among the SULTs, SULT4A1 localizes with mitochondria of neurons. Recent reports have suggested that this protein is believed play a protective role against oxidative stress. The goal of this project was to generate a SH-SY5Y cell line with a SULT4A1 gene deletion using CRISPR gene-editing technology. These neuroblastoma cells were used because of their ease ...

Ubiquitin E3 ligases are enzymes that mark certain substrates with ubiquitin proteins which leads to different cellular fates. Ring finger protein 216 (RNF216) is a ubiquitin E3 ligase that is involved in synaptic plasticity, inhibiting cellular autophagy, and the immune response in the peripheral nervous system. Previous literature has demonstrated that RNF216 participates in various aspects of inflammation by regulating ubiquitination and proteasomal degradation of receptor-interacting serine-threonine kinase 1 (RIPK1), toll-interleukin 1 receptor domain containing adaptor protein (TIRAP), and TIR-domain-containing adapter-inducing interferon-β (TRIF), targeting TNF receptor associated factor 3 (TRAF3) for degradation. TLRs initiate signal transduction pathways which can lead ...
