Identification and localization of alpha and beta spectrins in oocytes of three antarctic teleosts: Trematomus bernacchii, trematomus newnesi (Nototheniidae) and Chionodraco hamatus (Channichthyidae)
The presence and localization of α- and β-spectrins and of the spectrin cross-linking protein actin were investigated, in previtellogenic oocytes of three species of Antarctic teleosts: the two red-blooded nototheniids, Trematomus bernacchii and Trematomus newnesi, and the channichthyid, the ice fis...
