Periplanetasin-4, a novel antimicrobial peptide from the cockroach, inhibits communications between mitochondria and vacuoles
Novel long-chain neurotoxins from Bungarus candidus distinguish the two binding sites in muscle-type nicotinic acetylcholine receptors
Correction: Phosphorylation of CK1δ: identification of Ser370 as the major phosphorylation site targeted by PKA in vitro and in vivo
The cover image shows the secondary and tertiary structure of transfer RNA, including the two-dimensional clover-leaf structure describing the five domains which make up tRNA. In this issue Ontiveros and colleagues review the chemical diversity of RNA modifi cations. Image courtesy of Kathy Fange Liu.
