Abstract
DIXDC1 is a Dishevelled-Axin (DIX) domain-containing protein involved in neural development and Wnt signaling pathway. Besides the DIX domain, DIXDC1 also contains a coiled-coil domain (MTH domain), which is a common feature of centrosomal proteins. We have demonstrated that exogenously expressed GFP-tag fused DIXDC1 co-localize with γ-tubulin both at interphase and mitotic phase in HEK293 cells. By immunostaining with anti-DIXDC1 and anti-γ-tubulin antibody, endogenous DIXDC1 was also co-localized with γ-tubulin at the centrosomes in HEK293 cells. We confirmed this interaction of DIXDC1 with γ-tubulin by co-immunoprecipitation. The findings suggest that DIXDC1 might play an important role in chromosome segregation and cell cycle regulation.
