The central result was that the DYX1C1 and DCDC2 proteins physically interact with each other and with the centrosomal protein CPAP, and their genetic interaction exacerbates a ciliary phenotype in zebrafish.
Researchers demonstrated a physical protein-protein interaction between DYX1C1 and DCDC2, and their respective interactions with the centrosomal protein CPAP, using exogenous and endogenous systems in different cell models, including brain organoids. In zebrafish, a synergistic genetic interaction between dyx1c1 and dcdc2b was observed, which exacerbated a ciliary phenotype. A mutual effect on transcriptional regulation between DYX1C1 and DCDC2 was also shown in a cellular model. The study is limited by the need for further dissection of the DCDC2-CPAP interaction domain, rescue experiments in zebrafish, and confirmation of transcriptional regulation via overexpression. The findings contribute to understanding the molecular roles of these genes in cilia and neuronal migration, which are pathways implicated in dyslexia, but the evidence is indirect regarding human disease.
