WebApr 1, 2012 · As such, the inappropriate ciliary accumulation of proteins may imply an active removal pathway that is defective when the TZ is disrupted. Such a bidirectional gating is reminiscent of the nuclear pore complex, whose trafficking determinants, the Ran–Importin pathway, have been implicated in some aspects of ciliary trafficking [36]. 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. WebAll cilia are compartmentalized by a transition zone (TZ), a specialized gating structure found at cilia base, that controls the entry and exit of proteins, including receptors, and thereby the signaling properties of the primary cilium. ...

WebAug 7, 2024 · Being a stable component of the ciliary gating zone, NPHP5 may play a structural role and NPHP6 may regulate its turnover and/or function during ciliary gating. For NPHP4, its N-terminal region most likely occupies the most outer position within the ciliary gating zone as it interacts only with the transmembrane protein SSTR3 (Figure 7 A). 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.

WebAug 1, 2016 · Here, we discuss how specialized ciliary compartments are established using a coordinated network of gating, trafficking and targeting activities. Cilium homeostasis is maintained by a size-selective molecular mesh that limits soluble protein entry, and by a membrane diffusion barrier localized at the transition zone. 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).
