  • Actin & cytoskeleton regulation

Function

Role in ciliogenesis and tubulogenesis, acting as a guanine nucleotide exchange factor that regulates Cdc42 activity. Depletion results in an absence of cilia, with impaired apical polarisation. Controller of left-right patterning (26895965). TUBA/Cdc42/Par6A complex is required to ensure the formation of a single apical domain during enterocyte polarization ( 30408122). Knockdown of Dnmbp in MDCK cells leads to a decrease in cilia.
