Phosphorylation of Staphylococcus aureus Protein-Tyrosine Kinase Affects the Function of Glucokinase and Biofilm Formation
Background: When Staphylococcus aureus is grown in the presence of high concentration of external glucose, this sugar is phosphorylated by glucokinase (glkA) to form glucose-6-phosphate. This product subsequently enters into anabolic phase, which favors biofilm formation. The presence of ROK (repressor protein, open reading frame, sugar kinase) motif, phosphate-1 and -2 sites, and tyrosine kina...
متن کاملMinichromosome maintenance protein MCM7 is a direct target of the MYCN transcription factor in neuroblastoma.
The MYCN oncogene is amplified in approximately 25% of neuroblastoma tumors and is the most significant negative prognostic factor. The direct transcriptional targets of MYCN in MYCN-amplified tumors have not been defined. Microarray analysis of RNA from neuroblastoma primary cell cultures revealed 10-fold higher MCM7 expression in MYCN-amplified versus nonamplified tumors. MCM7 is an essential...
متن کاملThe Function of Calcium/calmodulin Dependent Protein Kinase Ii in Cell Cycle Regulation
Ca/Calmodulin-dependent protein kinase II (CamKII) is a multifunctional enzyme that is activated by increases in intracellular Ca. CaMKII is expressed in all tissues but is most abundant in the brain. Diversity in subunit composition and Ca sensitivity permit the coordination of multiple cellular functions including muscle contraction, synaptic vesicle release, proliferation and differentiation...
متن کاملImmunohistochemical evaluation of minichromosome maintenance protein 7 in astrocytoma grading.
The minichromosome maintenance (MCM) proteins, which play an important role in eukaryotic DNA replication, represent a group of proteins that are currently under investigation as novel diagnostic tumor markers. Several studies have proved a greater reliability of MCM proteins to stain proliferating cells compared to Ki67 protein, a routinely used proliferation marker in histopathology. In the p...
متن کاملPhosphorylation and cell cycle-dependent regulation of Na+/H+ exchanger regulatory factor-1 by Cdc2 kinase.
Na(+)/H(+) exchanger regulatory factor (NHERF)-1 is a PDZ domain-containing adaptor protein known to bind to various receptors, channels, cytoskeletal elements, and cytoplasmic signaling proteins. We report here that the phosphorylation state of NHERF-1 is profoundly regulated by the cell cycle: NHERF-1 in HeLa cells is hyperphosphorylated in mitosis phase and much less phosphorylated at other ...
