Irresistible curves

The DivIVA protein helps to organize cell growth and polarity in Gram-positive bacteria by localizing specifically to the cytoplasmic membrane at the cell poles and division septum, independent of other proteins. In this issue, Lenarcic et al suggest that DivIVA localization depends on the concave geometry of the membrane at those sites. This recognition of membrane curvature is reminiscent of ...

Irresistible IRES

Studies on the control of eukaryotic translation initiation by a cap-independent recruitment of the 40S ribosomal subunit to internal messenger RNA sequences called internal ribosome entry sites (IRESs) have shown that these sequence elements are present in a growing list of viral and cellular RNAs. Here we discuss their prevalence, mechanisms whereby they may function and their uses in regulat...

The Irresistible SRIQ

Motivated primarily by medical terminology applications, the prominent DL SHIQ has already been extended to a DL with complex role inclusion axioms of the form R ◦ S v̇ R or S ◦ R v̇ R, called RIQ, and the SHIQ tableau algorithm has been extended to handle such inclusions. This paper further extends RIQ and its tableau algorithm with important expressive means that are frequently requested in ont...
