Probing the molecular interactions of viral-host protein complexes to understand pathogenicity is essential in modern virology to help the development of antiviral therapies. Common binding assays, such as co-immunoprecipitation or pull-downs, are helpful in investigating intricate viral-host proteins interactions. However, such assays may miss

Polysome profile analysis is a popular method for separating polysomes and ribosomal subunits and is typically achieved using a sucrose density gradient (SDG). This has remained the gold standard method since ribosomes were first discovered; however, this method is time-consuming and requires multiple steps from making the gradient and long

Protein phosphorylation is a nearly universal signaling mechanism. To date, a number of proteomics tools have been developed to analyze phosphorylation. Phosphoproteome-wide analyses using whole cell extracts suffer from incomplete coverage, often missing phosphorylation events from low-abundance proteins. In order to increase coverage of

Cation-chloride cotransporters (CCCs) mediate the coupled, electroneutral symport of cations such as Na+ and/or K+ with chloride across membrane. Among CCCs family, K-Cl cotransporters (KCC1-KCC4) extrude intracellular Cl- by the transmembrane K+ gradient. In humans, these KCCs play vital roles in the physiology of the nervous system and kidney.

Initiation of the complement system results in the formation of a multiprotein pore termed the membrane attack complex (MAC, C5b-C9). MAC pores accumulate on a cell surface and can result in cell lysis. The retinal pigment epithelium (RPE) is a single monolayer of pigmented epithelial cells located at the posterior poll of the eye that forms the

The molecular mechanisms of P-glycoprotein (P-gp; also known as MDR1 or ABCB1) have been mainly investigated using artificial membranes such as lipid-detergent mixed micelles, artificial lipid bilayers, and membrane vesicles derived from cultured cells. Although these in vitro experiments help illustrate details about the molecular mechanisms of
