Subcellular Distribution of E2f3 Isoforms and Other Cell Cycle Proteins in the Developing Retina
Nuclear and cytoplasmic extracts from an equivalent number of retinal cells from mice of the indicated genotypes and ages were analyzed by Western blotting to detect the indicated proteins. Lysate from E2f3a−/− mice was used as a control to confirm the location of E2f3a protein. C, cytoplasmic extracts; N, nuclear extracts.
