With the discovery that the Saccharomyces cerevisiae Rad51 protein is both structurally and functionally similar to the Escherichia coli RecA protein, the RecA paradigm for homologous recombination was extended to the Eucarya. The ubiquitous presence of RecA and Rad51 protein homologs raises the question of whether this archetypal protein exists within the(More)
Nonenzymatic cytosolic fatty acid binding proteins (FABPs) are abundantly expressed in many animal tissues with high rates of fatty acid metabolism. No physiological role has been demonstrated for any FABP, although these proteins have been implicated in transport of free long-chain fatty acids (LCFAs) and protection against LCFA toxicity. We report here(More)
Melanocortin receptor accessory proteins (MRAPs) modulate signaling of melanocortin receptors in vitro. To investigate the physiological role of brain-expressed melanocortin 2 receptor accessory protein 2 (MRAP2), we characterized mice with whole-body and brain-specific targeted deletion of Mrap2, both of which develop severe obesity at a young age. Mrap2(More)
OBJECTIVE Familial glucocorticoid deficiency (FGD) is a rare autosomal recessive disease characterized by isolated glucocorticoid deficiency with preserved mineralocorticoid secretion. Mutations in the ACTH receptor (MC2R) account for approximately 25% of all FGD cases, but since these are usually missense mutations, a degree of receptor function is(More)
Receptor desensitization provides a potential mechanism for the regulation of adrenocortical adrenocorticotropin (ACTH) responsiveness. Using the mouse adrenocortical Y1 cell line we demonstrate that ACTH effectively desensitizes the cAMP response of its own receptor, the melanocortin 2 receptor (MC2R), in these cells with a maximal effect between 30 and 60(More)
Hypertension is a major risk factor for cardiovascular and cerebrovascular disease. Lifelong environmental factors (eg, salt intake, obesity, alcohol) and genetic factors clearly contribute to the development of hypertension, but it has also been established that stress in utero may program the later development of the disease. This phenomenon, known as(More)
The partial reinforcement extinction effect (PREE) refers to the increased resistance to extinction observed in animals trained on a partial reinforcement (PR) schedule compared with those trained on a schedule of continuous reinforcement (CR). It has been suggested that the PREE is dependent upon the integrity of the septo-hippocampal system, but recent(More)
Recently there has been an increase in research of hand gestures for interaction in the area of Augmented Reality (AR). However this research has focused on developer designed gestures, and little is known about user preference and behavior for gestures in AR. In this paper, we present the results of a guessability study focused on hand gestures in AR. A(More)
The RecA803 protein suppresses the recombinational repair defect of recF mutations and displays enhanced joint molecule formation in vitro (Madiraju et al., 1988). To understand the physical basis for these phenomena, the biochemical properties of RecA803 protein were compared with those of the wild-type protein. The RecA803 protein shows greater(More)
