A schistosome [beta] subunit remodels inactivation of a calcium channel _via_ an N-terminal polyacidic motif [PDF]
, 2010 The beta subunit of high voltage-activated Ca (Cav) channels targets the pore forming [alpha]~1~ subunit to the plasma membrane and defines the biophysical phenotype of the Cav channel complex. Cav channel inactivation following activation and opening is

The Embryonic Development of the Cotylean Polyclad Phrikoceros jannetae
Acta Zoologica, EarlyView.ABSTRACT Polyclads exhibit distinct developmental modes ranging from direct to indirect development, with several transitional stages also recognised. The existence of an indirect developmental mode in polyclads with a planktonic life history stage in the form of a free‐swimming larva is unique among all free‐living flatworms and makes polyclads a ...

Planarian (Platyhelminthes, Tricladida) Diversity and Molecular Markers: A New View of an Old Group
Diversity, 2014 Planarians are a group of free-living platyhelminths (triclads) best-known largely due to long-standing regeneration and pattern formation research. However, the group’s diversity and evolutionary history has been mostly overlooked.

Molecular cloning and characterization of growth factor receptor bound-protein in Clonorchis sinensis. [PDF]
PLoS ONE, 2014 BACKGROUND: Clonorchis sinensis causes clonorchiasis, a potentially serious disease. Growth factor receptor-bound protein 2 (Grb2) is a cytosolic protein conserved among animals and plays roles in cellular functions such as meiosis, organogenesis and ...

Single-Cell RNA Sequencing Atlas From a Bivalve Larva Enhances Classical Cell Lineage Studies
Frontiers in Ecology and Evolution, 2022 Ciliated trochophore-type larvae are widespread among protostome animals with spiral cleavage. The respective phyla are often united into the superclade Spiralia or Lophotrochozoa that includes, for example, mollusks, annelids, and platyhelminths ...

Assumption 0 analysis: comparative phylogenetic studies in the age of complexity [PDF]
, 2008 Darwin's panoramic view of biology encompassed two metaphors: the phylogenetic tree, pointing to relatively linear (and divergent) complexity, and the tangled bank, pointing to reticulated (and convergent) complexity.

Associations of Commercial Fisheries and Cold‐Water Corals and Sponges
Fish and Fisheries, EarlyView.Three metrics for determining whether the marine life that are landed by commercial fisheries are associated with cold‐water corals and sponges: (a) Adjacent; (b) General Proximity; and (c) Habitat. The relationship between these structure forming invertebrates (SFI) and fisheries is robust across analytical approaches.

Mitochondrial COI sequences in mites : evidence for variations in base composition [PDF]
, 1996 Studies of mitochondrial DNA sequences in a variety of animals have shown important differences between phyla, including differences in the genetic codes used, and varying constraints on base composition.
