A C-terminal motif found in the beta2-adrenergic receptor, P2Y1 receptor and cystic fibrosis transmembrane conductance regulator determines binding to the Na+/H+ exchanger regulatory factor family of PDZ proteins.
(Proc Natl Acad Sci U S A, 1998-07-21)The Na+/H+ exchanger regulatory factor (NHERF) binds to the tail of the beta2-adrenergic receptor and plays a role in adrenergic regulation of Na+/H+ exchange. NHERF contains two PDZ domains, the first of which is required ... -
A complex intronic enhancer regulates expression of the CFTR gene by direct interaction with the promoter.
(J Cell Mol Med, 2009-04)Genes can maintain spatiotemporal expression patterns by long-range interactions between cis-acting elements. The cystic fibrosis transmembrane conductance regulator gene (CFTR) is expressed primarily in epithelial cells. ... -
A membrane-associated progesterone-binding protein, 25-Dx, is regulated by progesterone in brain regions involved in female reproductive behaviors.
(Proc Natl Acad Sci U S A, 2000-11-07)The ventromedial hypothalamus (VMH) plays a central role in the regulation of the female reproductive behavior lordosis, a behavior dependent upon the sequential activation of receptors for the ovarian steroid hormones estradiol ... -
A miR-34a-Numb Feedforward Loop Triggered by Inflammation Regulates Asymmetric Stem Cell Division in Intestine and Colon Cancer.
(Cell Stem Cell, 2016-02-04)Emerging evidence suggests that microRNAs can initiate asymmetric division, but whether microRNA and protein cell fate determinants coordinate with each other remains unclear. Here, we show that miR-34a directly suppresses ... -
A novel human endogenous retroviral protein inhibits cell-cell fusion.
(Scientific reports, 2013-01)While common in viral infections and neoplasia, spontaneous cell-cell fusion, or syncytialization, is quite restricted in healthy tissues. Such fusion is essential to human placental development, where interactions between ... -
Binding of MetJ repressor to specific and nonspecific DNA and effect of S-adenosylmethionine on these interactions.
(Biochemistry, 2010-04-20)We have used analytical ultracentrifugation to characterize the binding of the methionine repressor protein, MetJ, to synthetic oligonucleotides containing zero to five specific recognition sites, called metboxes. For all ... -
cAMP stimulates transcription of the beta 2-adrenergic receptor gene in response to short-term agonist exposure.
(Proc Natl Acad Sci U S A, 1989-07)In addition to conveying cellular responses to an effector molecule, receptors are often themselves regulated by their effectors. We have demonstrated that epinephrine modulates both the rate of transcription of the beta ... -
cDNA for the human beta 2-adrenergic receptor: a protein with multiple membrane-spanning domains and encoded by a gene whose chromosomal location is shared with that of the receptor for platelet-derived growth factor.
(Proc Natl Acad Sci U S A, 1987-01)We have isolated and sequenced a cDNA encoding the human beta 2-adrenergic receptor. The deduced amino acid sequence (413 residues) is that of a protein containing seven clusters of hydrophobic amino acids suggestive of ... -
Classification and genetic characterization of pattern-forming Bacilli.
(Mol Microbiol, 1998-02)One of the more natural but less commonly studied forms of colonial bacterial growth is pattern formation. This type of growth is characterized by bacterial populations behaving in an organized manner to generate readily ... -
Cloning and expression of a human kidney cDNA for an alpha 2-adrenergic receptor subtype.
(Proc Natl Acad Sci U S A, 1988-09)An alpha 2-adrenergic receptor subtype has been cloned from a human kidney cDNA library using the gene for the human platelet alpha 2-adrenergic receptor as a probe. The deduced amino acid sequence resembles the human platelet ... -
Cloning of the cDNA for the human beta 1-adrenergic receptor.
(Proc Natl Acad Sci U S A, 1987-11)Screening of a human placenta lambda gt11 library has led to the isolation of the cDNA for the human beta 1-adrenergic receptor (beta 1AR). Used as the probe was the human genomic clone termed G-21. This clone, which contains ... -
Coordinated activation of candidate proto-oncogenes and cancer testes antigens via promoter demethylation in head and neck cancer and lung cancer.
(PLoS One, 2009)BACKGROUND: Epigenetic alterations have been implicated in the pathogenesis of solid tumors, however, proto-oncogenes activated by promoter demethylation have been sporadically reported. We used an integrative method to ... -
Desensitization, internalization, and signaling functions of beta-arrestins demonstrated by RNA interference.
(Proc Natl Acad Sci U S A, 2003-02-18)Beta-arrestins bind to activated G protein-coupled receptor kinase-phosphorylated receptors, which leads to their desensitization with respect to G proteins, internalization via clathrin-coated pits, and signaling via a ... -
Expansion of the alpha 2-adrenergic receptor family: cloning and characterization of a human alpha 2-adrenergic receptor subtype, the gene for which is located on chromosome 2.
(Proc Natl Acad Sci U S A, 1990-07)Pharmacologic, biochemical, and genetic analyses have demonstrated the existence of multiple alpha 2-adrenergic receptor (alpha 2AR) subtypes. We have cloned a human alpha 2AR by using the polymerase chain reaction with ... -
Finding regulatory DNA motifs using alignment-free evolutionary conservation information.
(Nucleic Acids Res, 2010-04)As an increasing number of eukaryotic genomes are being sequenced, comparative studies aimed at detecting regulatory elements in intergenic sequences are becoming more prevalent. Most comparative methods for transcription ... -
From offshore to onshore: multiple origins of shallow-water corals from deep-sea ancestors.
(PLoS One, 2008-06-18)Shallow-water tropical reefs and the deep sea represent the two most diverse marine environments. Understanding the origin and diversification of this biodiversity is a major quest in ecology and evolution. The most prominent ... -
G protein signaling and vein graft intimal hyperplasia: reduction of intimal hyperplasia in vein grafts by a Gbetagamma inhibitor suggests a major role of G protein signaling in lesion development.
(Arterioscler Thromb Vasc Biol, 1998-08)Vein grafting results in the development of intimal hyperplasia with accompanying changes in guanine nucleotide-binding (G) protein expression and function. Several serum mitogens that act through G protein-coupled receptors, ... -
Genetic evaluation of a proposed introduction: the case of the greater prairie chicken and the extinct heath hen.
(Mol Ecol, 2004-07)Population introduction is an important tool for ecosystem restoration. However, before introductions should be conducted, it is important to evaluate the genetic, phenotypic and ecological suitability of possible replacement ... -
