The gfzf gene is essential for viability and it has been identified in several genetic screenings pointed out its importance in different cellular processes. However, its molecular function has not been extensively studied so far. Here we analyse the GFZF protein interactome in Drosophila melanogaster embryos. The GFZF protein was subjected to immunoprecipitation with an antibody against the endogenous protein and the interactome was analysed by mass spectrometry. The samples are named as follows: antibody used _ batch _ MS ID _ date of MS run
