  • Title: Proteins with preferential affinity for single-stranded DNA in tissues of Octopus vulgaris lam.
    Author: Carsana A, Lavitrano ML, Libonati M.
    Journal: Ital J Biochem; 1984; 33(2):88-97. PubMed ID: 6539759.
    Abstract:
    An investigation was carried out to search for proteins with preferential affinity for single-stranded DNA in nuclei of testicles, white bodies and optic lobes of Octopus Vulgaris Lam, as examples of organs characterized by high meiotic, high mitotic, and no or low mitotic activity, respectively. The results obtained are the following. Single strand binding proteins are present in testicles nuclei and, in much lower amount, in white bodies nuclei. Testicles cells have at least three protein species with affinity for single-stranded DNA, which, on the basis of elution characteristics and electrophoretic mobility, appear to be specific of testicle tissue. No single strand binding proteins could be found in Octopus optic lobes nuclei.
