Abstract
Protein lipid modification involves the attachment of hydrophobic groups to proteins via ester, thioester, amide, or thioether linkages. In this review, the specific click chemical reactions that have been employed to study protein lipid modification and their use for specific labeling applications are first described. This is followed by an introduction to the different types of protein lipid modifications that occur in biology. Next, the roles of click chemistry in elucidating specific biological features including the identification of lipid-modified proteins, studies of their regulation, and their role in diseases are presented. A description of the use of protein-lipid modifying enzymes for specific labeling applications including protein immobilization, fluorescent labeling, nanostructure assembly, and the construction of protein-drug conjugates is presented next. Concluding remarks and future directions are presented in the final section.

Abstract
Protein myristoylation, the addition of a 14-carbon saturated acyl group, is an abundant modification implicated in biological events as diverse as development, immunity, oncogenesis, and infections. N-Myristoyltransferase (NMT) is the enzyme that catalyzes this modification. Many elegant studies have established the rules guiding the catalysis including substrate amino acid sequence requirements with the indispensable N-terminal glycine, and a co-translational mode of action. Recent advances in technology such as the development of fatty acid analogs, small molecule inhibitors, and new proteomic strategies, allowed a deeper insight into the NMT activity and function. Here we focus on discussing recent work demonstrating that NMT is also a lysine myristoyltransferase, the enzyme's regulation by a previously unnoticed solvent channel, and the mechanism of NMT regulation by protein-protein interactions. We also summarize recent findings on NMT's role in cancer, immunity, and infections and the advances in pharmacological targeting of myristoylation. Our analyses highlight opportunities for further understanding and discoveries.

Abstract
N-myristoyltransferase (NMT) attaches the fatty acid myristate to the N-terminal glycine of proteins to sort them into soluble and membrane-bound fractions. Function of the energy-sensing AMP-activated protein kinase, AMPK, is myristoylation dependent. In rheumatoid arthritis (RA), pathogenic T cells shift glucose away from adenosine tri-phosphate production toward synthetic and proliferative programs, promoting proliferation, cytokine production, and tissue invasion. We found that RA T cells had a defect in NMT1 function, which prevented AMPK activation and enabled unopposed mTORC1 signaling. Lack of the myristate lipid tail disrupted the lysosomal translocation and activation of AMPK. Instead, myristoylation-incompetent RA T cells hyperactivated the mTORC1 pathway and differentiated into pro-inflammatory TH1 and TH17 helper T cells. In vivo, NMT1 loss caused robust synovial tissue inflammation, whereas forced NMT1 overexpression rescued AMPK activation and suppressed synovitis. Thus, NMT1 has tissue-protective functions by facilitating lysosomal recruitment of AMPK and dampening mTORC1 signaling.

Abstract
Supplemental Digital Content is Available in the Text. Background: Antiretroviral drug discovery and formulation design will facilitate viral clearance in infectious reservoirs. Although progress has been realized for selected hydrophobic integrase and nonnucleoside reverse transcriptase inhibitors, limited success has been seen to date with hydrophilic nucleosides. To overcome these limitations, hydrophobic long-acting drug nanoparticles were created for the commonly used nucleoside reverse transcriptase inhibitor, lamivudine (2′,3′-dideoxy-3′-thiacytidine, 3TC). Methods: A 2-step synthesis created a slow-release long-acting hydrophobic 3TC. Conjugation of 3TC to a fatty acid created a myristoylated prodrug which was encased into a folate-decorated poloxamer 407. Both in vitro antiretroviral efficacy in human monocyte-derived macrophages and pharmacokinetic profiles in mice were evaluated for the decorated nanoformulated drug. Results: A stable drug formulation was produced by poloxamer encasement that improved monocyte–macrophage uptake, antiretroviral activities, and drug pharmacokinetic profiles over native drug formulations. Conclusions: Sustained release of long-acting antiretroviral therapy is a new therapeutic frontier for HIV/AIDS. 3TC depot formation in monocyte-derived macrophages can be facilitated through stable subcellular internalization and slow drug release.

Abstract
AIM A myristoylated abacavir (ABC) prodrug was synthesized to extend drug half-life and bioavailability. METHODS Myristoylated ABC (MABC) was made by esterifying myristic acid to the drug's 5-hydroxy-cyclopentene group. Chemical composition, antiretroviral activity, cell uptake and retention and cellular trafficking of free MABC and poloxamer nanoformulations of MABC were assessed by proton nuclear magnetic resonance and tested in human monocyte-derived macrophages. Pharmacokinetics of ABC and nanoformulated MABC were evaluated after intramuscular injection into mice. RESULTS MABC antiretroviral activity in monocyte-derived macrophages was comparable to native drug. Encasement of MABC into poloxamer nanoparticles extended drug bioavailability for 2 weeks. CONCLUSION MABC synthesis and encasement in polymeric nanoformulations improved intracellular drug accumulation and demonstrate translational potential as part of a long-acting antiretroviral regimen.
