Localization

EC Number Localization Comment Organism GeneOntology No. Textmining
3.4.22.B36 nucleus at cleavage cycles 8 and 9, when nuclei reach the egg surface, calpain is localized between the nuclei at the surface beneath the precleavage furrows. Calpain condenses specifically at the edge of and between actin caps that underlie the plasma membrane immediately above each nucleus Drosophila melanogaster 5634

3.4.22.B36 embryo calpain is first detected near the anterior pole and in posterior region of the embryo just after fertilization. The anterior calpain disappears during the cleavage cycles. On the other hand, the posterior calpain moved to the posterior pole when polar buds are formed, and condenses just below the pole cells. At cleavage cycles 8 and 9, when nuclei reach the egg surface, calpain is localized between the nuclei at the surface beneath the precleavage furrows. Calpain condenses specifically at the edge of and between actin caps that underlie the plasma membrane immediately above each nucleus Drosophila melanogaster
