"WebFeb 12, 2024 · A range of severe human diseases called ciliopathies are caused by the dysfunction of primary cilia. Primary cilia are cytoplasmic protrusions consisting of the basal body (BB), the axoneme and the transition zone (TZ). The BB is a modified mother centriole from which the axoneme, the microtubule-based ciliary scaffold, is formed. At the … " - Ciliary gating

WebApr 6, 2024 · (D) ANKRD26 and ciliary gating. The cilia transition fiber protein ANKRD26 allows the ciliary gating of GPCRs. ANKRD26 comprises this gate with TALPID3 and FBF1 and this gating complex facilitates ciliary GPCR import. A lack of Ankrd26 induces severe obesity and hyperphagia due to the reduced ciliary expression of MC4R and other GPCRs. WebDec 13, 2024 · In their manuscript, "ERK pathway activation inhibits ciliogenesis and causes defects in motor behavior, ciliary gating, and cytoskeletal rearrangement," Dougherty et al investigate how BCI, an activator of MAPK signaling, regulates ciliary length.
