Adducin is a heteromeric protein with subunits containing a COOH-terminal myristoylated alanine-rich C kinase substrate (MARCKS)-related domain that caps and preferentially recruits spectrin to the fast-growing ends of actin filaments. The basic MARCKS-related domain, present in alpha, beta, and gamma adducin subunits, binds calmodulin and contains the major phosphorylation site for protein kin...

Previous studies have demonstrated that microRNA (miR)‑34c‑3p is important in human cancer progression. However, the function of miR‑34c‑3p in osteosarcoma (OS) remains to be elucidated. In the present study, miR‑34c‑3p level was measured by reverse transcription‑quantitative polymerase chain reaction in OS tissues and the associated prognostic value for overall survival was determined. The fun...

The localization of MARCKS (myristoylated, alanine-rich C-kinase substrate), a major specific substrate for protein kinase C, has been studied in the rat brain. Light microscopic immunocytochemistry and biochemical analysis demonstrated that the protein is widespread throughout the brain and enriched in certain regions, including the piriform and entorhinal cortices, portions of the amygdaloid ...

The growing use of cochlear prosthetic devices and demonstrations of direct ototoxic insult to spiral ganglion neurons make it imperative to gain an understanding of intracellular biochemical regulation in primary sensory neurons. Calcium and calmodulin regulate many aspects of neuronal cellular physiology through stimulation of protein kinase activity. We have previously demonstrated the prese...

Adducin is a ubiquitously expressed actin- and spectrin-binding protein involved in cytoskeleton organization, and is regulated through phosphorylation of the myristoylated alanine-rich C-terminal kinase (MARCKS)-homology domain by protein kinase C (PKC). We have previously shown that the Drosophila adducin, Hu-li tai shao (Hts), plays a role in larval neuromuscular junction (NMJ) growth. Here,...

Chemotherapeutic prodrugs have demonstrated success in killing cancer cells; however they also pose harm to healthy cells. The objective of this project was to synthesize an improved prodrug that is selectively activated only in the cancer microenvironment, thus minimally affecting healthy tissue. A photolabile linker was hypothesized to achieve said objective. The Yin group discovered that the...

We describe a new approach to calculate the binding of flexible peptides and unfolded proteins to multicomponent lipid membranes. The method is based on the transfer matrix formalism of statistical mechanics recently described as a systematic tool to study DNA-protein-drug binding in gene regulation. Using the energies of interaction of the individual polymer segments with different membrane li...

Intracellular protein-protein interactions are dynamic events requiring tightly regulated spatial and temporal checkpoints. But how are these spatial and temporal cues integrated to produce highly specific molecular response patterns? A helpful analogy to this process is that of a cellular map, one based on the fleeting localization and activity of various coordinating proteins that direct a wi...
