Unwrapping the Ciliary Coat: High-Resolution Structure and Function of the Ciliary Glycocalyx.

The glycocalyx, a highly heterogeneous glycoprotein layer of cilia regulates adhesion and force transduction and is involved in signaling. The high-resolution molecular architecture of this layer is currently not understood. The structure of the ciliary coat is described in the green alga Chlamydomonas reinhardtii by cryo-electron tomography and proteomic approaches and the high-resolution cryoEM structure of the main component, FMG1B is solved.
