Proteomic Studies of Various Organs and Tissues of the Frilled Shark Chlamydoselachus anguineus

Feico M.A.H. Schuurmans Stekhoven, Tsung-Han Lee, Pei-Jen Wang, Nian-Hong Jang-Liaw, Sho Tanaka, and Andrew R. Bottrill (2012) In a search for the presence or absence of the Cl^- channel phospholemman in 9 different tissues from organs of the most ancient shark on earth (Chlamydoselachus anguineus), we came to the conclusion that these did not contain the Cl^- channel we sought.  On the other hand, a large variety of proteins involved in cellular signaling and transport regulation were detected (36.7% of all analyzed protein components), suggesting that in its long history, C. anguineus has developed proteins chemically and mechanistically similar to those of modern sharks.
