The crystal structure of the NTF2-like domain of the Drosophila homolog of Ras GTPase SH3 Binding Protein (G3BP), Rasputin, was determined at 2.7Å resolution. The overall structure is highly similar to nuclear transport factor 2: It is a homodimer comprised

A typical feature of astrocytes is their high level of connexin expression. These membrane proteins constitute the molecular basis of two types of channels: gap junction channels that allow direct cytoplasm-to-cytoplasm communication and hemichannels that provide a pathway for exchanges
