XMM-Newton spots a black hole throwing a tantrum

Black holes are like temperamental toddlers. They spill food all the time, but ESA's XMM-Newton has caught a black hole in the act of "flipping over the table" during an otherwise civilized meal.

'Sandwich' discovery offers new explanation for planet formation

Scientists have made a new discovery on how small planets might form. Researchers at the University of Warwick investigated the "birth environment" of planets—areas of gas and dust that swirl around a central star—known ...

Flaring star could be down to young planet's disk inferno

The mystery of a stellar flare a trillion times more powerful than the largest of solar flares may have been solved by a team of scientists who believe a massive young planet is burning up in a superheated soup of raw material ...

Researchers confirm a new forming planet

A study led by Monash University astronomers published new near-infrared images of the system HD 169142, which enabled the confirmation of a protoplanet forming in the system.

PSD-95 (postsynaptic density protein 95) also known as SAP-90 (synapse-associated protein 90) is a protein that in humans is encoded by the DLG4 (disks large homolog 4) gene.

PSD-95 is a member of the membrane-associated guanylate kinase (MAGUK) family. With PSD-93 it is recruited into the same NMDA receptor and potassium channel clusters. These two MAGUK proteins may interact at postsynaptic sites to form a multimeric scaffold for the clustering of receptors, ion channels, and associated signaling proteins.

PSD-95 is the best studied member of the MAGUK-family of PDZ domain-containing proteins. Like all MAGUK-family proteins, its basic structure includes three PDZ domains, an SH3 domain, and a guanylate kinase-like domain (GK) connected by disordered linker regions. It is almost exclusively located in the post synaptic density of neurons, and is involved in anchoring synaptic proteins. Its direct and indirect binding partners include neuroligin, NMDA receptors, AMPA receptors, and potassium channels.
