Aberrant PCM1 accumulation in Trisomy 21 mislocalizes E3 ligases, delaying primary ciliogenesis

Primary cilia are microtubule-based extracellular signaling structures essential for development and tissue homeostasis, and their defects can cause ciliopathies. Trisomy 21, the cause of Down syndrome, also disrupts cilia formation and function. Here we show that Pericentrin (PCNT), a chromosome 21 resident gene whose...

SPEF1 mediates assembly of central pair microtubule complexes in cilia of Tetrahymena.

SPEF1 is a conserved calponin-homology domain protein that decorates the seam of central pair microtubules in the distal segment of motile cilia. Here, we show that in the ciliate Tetrahymena, loss of SPEF1 disrupts the central pair throughout the middle segment, which comprises most of the cilium, producing gaps in th...
