Vertebrate muscle differentiation is coordinated by an intricate network of transcription factors requiring proliferating myogenic precursors to withdraw irreversibly from the cell cycle. Recent studies have implicated a large number of microRNAs exerting another layer of control in many aspects of muscle differentiation. By annealing to short recognition(More)
Myosin heavy chain kinase A (MHCK A) in Dictyostelium was identified as a biochemical activity that phosphorylates threonine residues in the myosin II tail domain and regulates myosin filament assembly. The catalytic domain of MHCK A has now been mapped through the functional characterization of a series of MHCK A truncation mutants expressed in Escherichia(More)
Dictyostelium myosin II heavy chain kinase A (MHCK A), MHCK B, and MHCK C contain a novel type of protein kinase catalytic domain that displays no sequence identity to the catalytic domain present in conventional serine, threonine, and/or tyrosine protein kinases. Several proteins, including myelin basic protein, myosin regulatory light chain, caldesmon,(More)
Examination of the structure of [Arg(8)]-vasopressin receptors (AVPRs) and oxytocin receptors (OTRs) suggests that G protein-coupled receptor kinases (GRKs) and protein kinase C (PKC) are involved in their signal transduction. To explore the physical association of AVPRs and OTRs with GRKs and PKC, wild types and mutated forms of these receptor subtypes(More)
OBJECTIVE To study solubility enhancement of curcumin by Polyvinylpyrrolidione K30 (PVP K30). METHODS Solid dispersion systems (SDS) of curcumin in PVP K30 were prepared at various weight ratios by co-evaporation of curcumin and PVP K30 ethanol solution. The differential scanning calorimetry (DSC) and powder X-ray diffractometer method were used to(More)
