High impact information on Pclo

  • Analysis of the amino acid sequences of chicken and mouse aczonin indicates an organization into multiple domains, including two pairs of Cys(4) zinc fingers, a polyproline tract, and a PDZ domain and two C2 domains near the COOH terminus [1].
  • We report the identification and initial characterization of aczonin, a neuron-specific 550-kD protein concentrated at the presynaptic active zone and associated with a detergent-resistant cytoskeletal subcellular fraction [1].
  • Munc13 bound to the zinc finger domain of Rim1 but not to the rabphilin-3 or aczonin zinc fingers [2].
  • Pico-rna-virus stands for viruses which are small (pico), and have an RNA genome [3].
 

Analytical, diagnostic and therapeutic context of Pclo

  • The structures of 1 and 2 were assigned based upon their amino acid analyses on a Waters Pico Tag HPLC system and a chiral GC capillary column (Chirasil Val III), fast atom bombardment mass spectrometry (FABMS), high resolution FABMS, and tandem FABMS data [4].
  • Structures of these compounds were assigned based on their amino acid analysis with a Waters Pico Tag HPLC system plus fast atom bombardment mass spectrometry (FABMS), including tandem FABMS, analysis on the two new microcystins, [D-Glu(OCH3)6]microcystin-LR (1) and [D-Asp3, D-Glu(OCH3)6]microcystin-LR (2) [5].
