The RNA-binding protein CsrA (carbon storage regulator) is a new kind of global regulator, which facilitates specific mRNA decay. A recombinant CsrA protein containing a metal-binding affinity tag (CsrA-H6) was purified to homogeneity and authenticated by N-terminal sequencing, matrix-assisted laser desorption/ionization time of flight mass spectrometry, and other studies. This protein was enti...

Aichi target 11 of the Convention of Biological Diversity promotes the expansion of the global protected area network to cover 17 percent of all terrestrial land and 10 percent of coastal and marine areas by 2020 (www.cbd.int/sp/targets). At the recent World Parks Congress, organized by the International Union for Conservation of Nature (IUCN) in Sydney, Australia, 12 innovative approaches wer...

A study of the lipids of Pithomyce8 chartarum (Berk. & Curt.) M. B. Ellis (which has replaced the name Sporide8mium bakeri Syd. used previously) has shown that their fatty acid composition differs from that of other fungi hitherto examined in containing large quantities of both linoleic acid and palmitic acid (Hartman, Hawke, Morice & Shorland, 1960). The main object of the present work has bee...

Liprin-alpha/SYD-2 is a family of multidomain proteins with four known isoforms. One of the reported functions of liprin-alpha is to regulate the development of presynaptic active zones, but the underlying mechanism is poorly understood. Here we report that liprin-alpha directly interacts with the ERC (ELKS-Rab6-interacting protein-CAST) family of proteins, members of which are known to bind RI...

Receptor protein tyrosine phosphatases include the leukocyte-common antigen related (LAR) family of cell adhesion molecules. In Caenorhabditis elegans, the LAR-like gene ptp-3 encodes two distinct isoforms, PTP-3A and PTP-3B. Compared with PTP-3A, the extracellular domain of PTP-3B lacks the Ig-like domain and the first four fibronectin type III repeats, but their intracellular domains are iden...
