Nuclear FBPase was identified as muscle chicken FBPase.

The article focuses on a report, which describes the localization of chicken muscle FBPase in cardiomyocyte nuclei. M. Zmojdzian and colleagues of the University of Wroclaw reported that a result of the electron microscopic investigation was confirmed by immunoblotting analysis. Using MALDI Q-TOF mass spectrometry and the Mascot program, the nuclear FBPase was identified as muscle chicken FBPase. FBPase activity in isolated cardiomyocyte nuclei was 5.9 mU/g. Zmojdzian and colleagues published the results of their research in "Comparative Biochemistry and Physiology B - Biochemistry & Molecular Biology."
