Among the 20 subfamilies of protein receptor tyrosine kinases (RTKs), Eph receptors are unique in possessing a sterile alpha motif (SAM domain) at their C-terminal ends. However, the functions of SAM domains in Eph receptors remain elusive. Here we report on a combined cell biology and quantitative fluorescence study to investigate the role of the SAM domain in EphA2 function. We observed eleva...
Social accounting matrices (SAMs) have been used fairly extensively to model the effects of shocks on a nation's economy. A brief literature review on SAMs and examples of their use for simple simulations were provided by Parra and Wodon (2009b) in chapter 6 of this volume. That chapter highlighted the strengths and weaknesses of SAMs and emphasized the need to be care ful before using SAM-bas...
T paper describes a decision tree analysis to assess the cost-effectiveness of MANPADS (Man-Portable Air Defense Systems) countermeasures. These countermeasures are electronic devices that can be installed on commercial airplanes to detect and deflect surface-to-air missiles (SAMs) fired by terrorists. The model considers a terrorist attempt to shoot down a commercial airplane with a heat-seeki...
In this application note the NanoArrayerTM is used to print proteins onto various surface types including hydrogel, nitrocellulose, and chemically treated surfaces such as silanes and self-assembling monolayers (SAMs). This demonstrates the utility of these surfaces as printing substrates for a variety of potential applications, some of which may require a flat silane or SAM surface while other...
Stromal interaction molecules (STIM)s function as endoplasmic reticulum calcium (Ca(2+)) sensors that differentially regulate plasma membrane Ca(2+) release activated Ca(2+) channels in various cells. To probe the structural basis for the functional differences between STIM1 and STIM2 we engineered a series of EF-hand and sterile α motif (SAM) domain (EF-SAM) chimeras, demonstrating that the ST...
MOTIVATION SAM-T99 is an iterative hidden Markov model-based method for finding proteins similar to a single target sequence and aligning them. One of its main uses is to produce multiple alignments of homologs of the target sequence. Previous tests of SAM-T99 and its predecessors have concentrated on the quality of the searches performed, not on the quality of the multiple alignment. In this p...
OBJECTIVE Automated adaptive spatial filtering techniques can be applied to magnetoencephalographic (MEG) data collected from people with epilepsy. Source waveforms estimated by these methods have higher signal-to-noise ratio (SNR) than spontaneous MEG data, allowing identification and location of interictal spikes. The software tool SAM(g(2)) provides an adaptive spatial filtering algorithm fo...
The shoot apical meristem (SAM) maintains a pool of indeterminate cells within the SAM proper, while lateral organs are initiated from the SAM periphery. Laser microdissection-microarray technology was used to compare transcriptional profiles within these SAM domains to identify novel maize genes that function during leaf development. Nine hundred and sixty-two differentially expressed maize ge...
