Exploring The Chemical And Biological Foundations Of Protein Lipidation Through Functional And Computational Studies, Andrea Sprague-Getsy

Dissertations - ALL

Post-translational modifications (PTMs) are essential for the diversification of the human proteome. Prenylation is a PTM defined by the addition of a 15-carbon or 20 carbon isoprenoid group by FTase and GGTase-I, respectively, onto a cysteine near the C-terminus of proteins. This modification is the first step within the prenylation pathway where proteolysis and carboxymethylation occur afterwards, aiding in proteins localization to the cellular membrane. These prenyltransferases canonically recognize a “CaaX” box motif which has been determined through biochemical and structural studies. Recently, sequences following the C(x)3X and Cxx patterns have been shown to be prenylated as well as an …

All Decisions

In this licensee holdover, the tenant moved to disqualify the landlord's counsel, arguing a conflict of interest because one of the firm's attorneys previously represented the tenant in a substantially related prior proceeding. The court found that a presumption of disqualification arose, but the landlord rebutted it by demonstrating that the attorney lived out of state, was not involved in the current proceeding, did not possess material information, and the firm had established an ethical wall. The court denied the tenant's motion but prohibited the firm from discussing the case with the attorney in question.
