tRNA prefers to kiss.
Six RNA aptamers that bind to yeast phenylalanine tRNA were identified by in vitro selection from a random-sequence pool. The two most abundantly represented aptamers interact with the tRNA anticodon loop, each through a sequence block with perfect Watson-Crick complementarity to the loop. It was possible to truncate one of these aptamers to a simple hairpin loop that forms a classical 'kissing...
متن کاملKiss of death
Kiss of death D8 cytotoxic T cells are serial killers that slay one infected or cancerous cell after another. During each fatal encounter, an intercellular junction called the immunological synapse forms between killer and victim, according to researchers from Oxford University (Oxford, UK). Their work suggests new functions for the immunological synapse and supports the hypothesis that the imm...
متن کاملThe kiss of death.
The kiss of death Cellular suicide is a grave matter, motivating researchers to a thorough exploration of the genetic pathways involved. Of the three main means by which cells die, most in the scientific community are quite familiar with the genetically regulated apoptotic pathway (1). Autophagy, in which the cell literally digests itself, is likewise now also recognized as a form of regulated ...
متن کاملThe Kiss of Death
The programmed cell death (PCD) of neurons is generally thought to be cell autonomous and not to require a death signal from other cells. A recent study by Marín-Teva et al., in this issue of Neuron, brings this theory into question and suggests that neighboring microglia actively participate in the PCD of Purkinje cells in the cerebellum.
متن کاملPrelude to a Kiss
We consider expanding maps of the circle with an almost neutral fixed point c. In this setting the ergodic averages of a smooth observable A satisfy the Central Limit Theorem. If A(c) = 0 we show that the expectation and the variance behave as the square root of the multiplier of c times rapidly oscillating functions of parameters.
