Description:

Protein palmitoylation is an essential post-translational modification necessary for trafficking and localization of regulatory proteins that play key roles in cell growth and signaling. Numerous proteins have been identified as targets of palmitoylation, including cytoskeletal proteins, kinases, receptors, and other proteins involved in various aspects of cellular signaling and homeostasis [1]. Using a global chemo-proteomic method for the metabolic incorporation and identification of palmitoylated proteins, we were able to identify hundreds of palmitoylated proteins, revealing palmitoylation as a widespread post-translational modification (PTM) [2]. Palmitoylation involves an acyl-thioester linkage to specific cysteines [3,4]. Given the labile properties of thioesters, palmitoylation is potentially reversible and may be regulated in a manner analogous to other PTMs (e.g., phosphorylation). As such, identification of proteins responsible for the dynamic modulation of palmitoylation is paramount to understanding its patho/physiological roles. For example, multiple oncogenes, including HRAS and SRC, require palmitoylation for malignant transformation [5], suggesting protein palmitoyl thioesterases may have tumor suppressor activity required to repress aberrant growth signaling. More than a decade ago, the cytosolic serine hydrolase acyl-protein thioesterase 1 (APT1) was identified as an in vitro HRAS palmitoyl thioesterase [6]. Initially classified as lysophospholipase 1 (LYPLA1) [7], the enzyme has since been demonstrated to have several hundred-fold higher activity as a protein thioesterase. While the in vitro data [6,8] provided an intriguing clue to its possible role in vivo, prior to our studies, little was known about the in vivo thioesterase activity of LYPLA1. Upon retroviral shRNA knockdown of LYPLA1, we found that HRAS was robustly hyper-palmitoylated, providing the first evidence that the endogenous enzyme is a functional protein palmitoyl thioesterase capable of regulating HRAS palmitoylation in mammalian cells. However, shRNA resulted in only an 80% reduction in LYPLA1 expression (unpublished). LYPLA2 (a.k.a. APT2) is 65% identical to LYPLA1, and also exhibits lysophospholipase activity in vitro, but its potential role as a thioesterase is unknown [9]. shRNA knockdown studies of LYPLA2 revealed only partial knockdown of the enzyme, making substrate identification inconclusive (unpublished). A principle goal of post-genomic research is the determination of the molecular and cellular role of uncharacterized enzymes like LYPLA1 and LYPLA2. As such, selective inhibitors of LYPLA1 and/or LYPLA2 would greatly aid investigations into the biological function of these enzymes. Several inhibitors of LYPLA1 have been described [10,11], but none of these agents have proven capable of inhibiting LYPLA1 activity in cells. We recently reported optimization of a covalent dual LYPLA1/LYPLA2 inhibitor ML211, and identification of reversible compounds ML348 and ML349 that act as selective LYPLA1 and LYPLA2 inhibitors, respectively (see Probe Reports). These compounds represent an important advance in chemical tools for investigating the biological function(s) of LYPLA1 and LYPLA2. However, ML211, owing to its modest solubility, does not have demonstrated in vivo activity. Irreversible chemical probes have distinct advantages vs. reversible compounds for use in living systems, as confirming target engagement is a comparatively straightforward process, and near-complete and sustained target inhibition can be achieved without extensive optimization of physicochemical and pharmacokinetic properties. The goal of this current investigation is to develop an irreversible, in vivo-active dual LYPLA1/LYPLA2 inhibitor to add to the arsenal of available chemical tools for identification of LYPLA1 and LYPLA2 substrates and evaluating the role of these enzymes in dynamic de-palmitoylation and tumorigenesis.

Protocol
Assay Overview:
The purpose of this assay is to determine IC50 values of powder samples of test compounds for LYPLA1 (Assay 1) and LYPLA2 (Assay 2) in a complex proteomic lysate using an activity-based proteomic profiling (ABPP) assay. In this assay, a complex proteome is incubated with test compound followed by reaction with a serine hydrolase-specific rhodamine-conjugated fluorophosphonate (FP-Rh) activity-based probe. The reaction products are separated by SDS-PAGE and visualized in-gel using a flatbed fluorescence scanner. The percentage activity remaining is determined by measuring the integrated optical density (IOD) of the bands. As designed, test compounds that act as LYPLA1 and/or LYPLA2 inhibitors will prevent enzyme-probe interactions, thereby decreasing the proportion of bound fluorescent probe, giving lower fluorescence intensity in the band in the gel. Percent inhibition is calculated relative to a DMSO (no compound) control. Compounds are tested in triplicate in a 5-point 1:10 dilution series starting at a nominal concentration of 10000 nM.
Protocol Summary:
Soluble proteome (50 uL reaction volume) prepared from HeLa cell lysates (1 mg/mL in DPBS) was treated with 10000 nM, 1000 nM, 100 nM, 10 nM, or 1 nM test compound (1 uL of a 50x stock in DMSO) for 30 minutes at 37 degrees Celsius. FP-Rh (1 uL of 50x stock in DMSO) was added to a final concentration of 2 uM. The reactions were incubated for 30 minutes at 25 degrees Celsius, quenched with 16 microL 4x SDS-PAGE loading buffer (reducing), separated by SDS-PAGE and visualized by in-gel fluorescent scanning. The percentage activity remaining was determined by measuring the integrated optical density of the target and anti-target bands relative to a DMSO-only (no compound) control. IC50 values were determined from dose-response curves from three replicates at each inhibitor concentration.
%_Inhibition = ( 1 - ( IOD_Test_Compound - IOD_Low_Control ) / ( IOD_High_Control - IOD_Low_Control ) ) * 100
Where:
Test_Compound is defined as target treated with test compound.
High_Control is defined as target treated with DMSO only (no compound).
Low_Control is defined as background in a blank region of the gel.
For each test compound, percent inhibition was plotted against the log of the compound concentration. A three parameter equation describing a sigmoidal dose-response curve was then fitted using GraphPad Prism (GraphPad Software Inc). The software-generated IC50 values are reported. In the event that the highest test concentration did not result in at least 50% inhibition, the IC50 value is reported as being greater than the highest test concentration.
Assay Outcome:
Compounds with an IC50 less than or equal to 1 uM were considered active. Compounds with an IC50 greater than 1 uM were considered inactive.
PubChem Activity Outcome and Score:
Compounds were considered active if they were active in both assays. Compounds were considered inactive if they were inactive in one or both assays.
The PubChem Activity Score range for active compounds is 100-1, there are no inactive compounds.
