High impact information on Squalus

  • Distinct CCK and gastrin peptides were identified in two shark species, the spiny dogfish (Squalus acanthias) and the porbeagle (Lamna cornubica) [1].
  • Although the steroid binding and sedimentation properties of the Squalus nuclear ER conformed to those of classical ER, its elution maximum from DNA-cellulose was unusually high (0.55 M NaCl) [2].
  • An estrogen (E)-binding molecule having both occupied and unoccupied sites is restricted to nuclear subfractions in the testis of the spiny dogfish (Squalus acanthias) [2].
  • A novel 15-kDa protein, sharing considerable homology to the gamma-subunit and to phospholemman (PLM) was identified in purified Na,K-ATPase preparations from rectal glands of the shark Squalus acanthias, but was absent in pig kidney preparations [3].
  • Nucleotide sequence and tissue-specific expression of the multifunctional protein carbamoyl-phosphate synthetase-aspartate transcarbamoylase-dihydroorotase (CAD) mRNA in Squalus acanthias [4].
