Updated project metadata. To determine the mechanism for how Kctd10 deficiency impacts brain development, co-immunoprecipitation (co-IP) was performed to identify KCTD10-interacting proteins from the E14.5 cerebral cortex using a KCTD10 antibody, followed by mass spectrometric analysis. In total, 143 proteins uniquely precipitated by the KCTD10 antibody were detected.
