In children, lack of a protein causes a dangerous disease. Why do cancer cells suppress the same protein?

To understand the relationships between the “words” encoded in the retinal responses to film clips, the researchers analyzed and plotted them on a 3-D graph on which they attempted to preserve the relations between the words. Each balloon covers all the words that belong to the same sematic cluster. The fact that the balloons are so distinct shows the underlying “synonym” organization of neuron communication

op: Mass spectrometry, along with other methods, reveals that the protein CSNAP is the ninth subunit of the COP9 signalosome (CSN) complex. Bottom: COP9 complex subunits compared with those of the 19S proteasome suggest that CSNAP is the corresponding subunit to the smallest proteasome protein, filling in the puzzle of the “missing piece
