Corolla is a novel protein that contributes to the architecture of the synaptonemal complex of Drosophila

Genetics. 2014 Sep;198(1):219-28. doi: 10.1534/genetics.114.165290. Epub 2014 Jun 9.


In most organisms the synaptonemal complex (SC) connects paired homologs along their entire length during much of meiotic prophase. To better understand the structure of the SC, we aim to identify its components and to determine how each of these components contributes to SC function. Here, we report the identification of a novel SC component in Drosophila melanogaster female oocytes, which we have named Corolla. Using structured illumination microscopy, we demonstrate that Corolla is a component of the central region of the SC. Consistent with its localization, we show by yeast two-hybrid analysis that Corolla strongly interacts with Cona, a central element protein, demonstrating the first direct interaction between two inner-synaptonemal complex proteins in Drosophila. These observations help provide a more complete model of SC structure and function in Drosophila females.

Keywords: chromosome segregation; meiosis; next-generation sequencing; structured illumination microscopy; synaptonemal complex.
