Abstract

The major nucleoside triphosphatase of rat liver nuclear scaffold, a 46 kD protein thought to participate in nucleocytoplasmic RNA translocation, is distinct from immunologically-identified scaffold actin on Western blots, has a substantially different amino acid composition, and its enzymatic activity is not affected by anti-actin antibodies. Thus, although the contractile protein actin is found in nuclear scaffold and appears to interact with RNA, it is not associated with the nucleoside triphosphatase activity in such preparations.
