• An extracellular matrix protein prevents cytokinesis failure and aneuploidy in the C. elegans germline 

  Vogel, Bruce E.; Wagner, Cynthia; Paterson, Joanna Mathis; Xu, Xuehong; Yanowitz, Judith L. (Taylor & Francis, 2011-06-15)

  We have identified, purified, and characterized a high-mobility-group (HMG) protein and its cDNAs from Drosophila melanogaster. This protein, HMG D, shares most of the characteristics of vertebrate HMG proteins; it is ...

• Germ Cells and Epigenetics 

  Wagner, Cynthia R.

  All multicellular organisms begin life as a single cell, the zygote, created by the union of two germ cells, an oocyte and a sperm. Although scientists have understood for decades that the quantity of DNA an individual ...

• One of the two cytoplasmic actin isoforms in Drosophila is essential 

  Wagner, Cynthia R.; Mahowald, Anthony P.; Miller, Kathryn G. (The National Academy of Sciences, 2002-05-28)

  Actin is a highly conserved protein found in all eukaryotic organisms. Most organisms have multiple cytoplasmic actin genes that encode isoforms with slightly different amino acid sequences. These different isoforms are ...
