WebCIB2 and CIB3 bind to TMC1/2 through a domain in TMC1/2 flanked by transmembrane domains 2 and 3. The co-crystal structure of the CIB-binding domain in TMC1 with CIB3 reveals that interactions are mediated through a conserved CIB hydrophobic groove, similar to KChIP1 binding of K4. Functional studies in mice show that CIB2 regulates TMC1/2 ...

WebBy determining the crystal structures of CIB3 and its complex with a TMC1- peptide, we were able to visualize the molecular determinants that allow CIB3 to interact with itself and TMC1. We demonstrate that CIB2 mutations affect the single channel conductance of the MET channel, indicating that CIB2 is a regulator of the MET complex. WebScientist. Apr 2024 - Jan 20241 year 10 months.

WebAug 5, 2024 · Two genes, Cib2 and Cib3, were identified in the protein-protein interaction with TMC1. The nematode consists only of calm-1, orthologous to both mammalian Cib2 and Cib3 genes. A strong interaction between TMC-1 N terminus and CALM-1 by the pull-down assay suggested that the conserved proteins are involved in mechanosensation.
