Transport systems specific for L-glutamate and L-aspartate play an important role in the termination of neurotransmitter signals at excitatory synapses. We describe here the structure and function of
Cerebral infarct (stroke) often causes devastating and irreversible losses of function, in part because of the brain's limited capacity for anatomical reorganization. The purine nucleoside inosine has
The replication of bovine papilloma virus (BPV) DNA in vivo requires two viral-encoded proteins, E1 and E2, while all other proteins are derived from the host. We described previously the isolation of
AU-rich sequence motifs (specifically sequences containing reiterations of AUUUA) are found in the 3' untranslated region of mammalian mRNAs encoding cytokines, adhesion molecules, and protooncogenes.
A vitamin K-dependent carboxylase has recently been purified from bovine liver microsomes and candidate cDNA clones have been isolated. Definitive identification of the carboxylase remains circumstant
