IF140, C-terminal TPR domain
InterPro entry
Short name | TPR_IF140_C |
Description
This entry represents the TPR domain found at the C-terminal of IFT140.
IFT140 is one of the core components (together with WDR19/IFT144 and IFT122) of the IFT-A complex which is required for retrograde ciliary transport and entry into cilia of G protein-coupled receptors (GPCRs), being involved in cilia function and/or assembly
[2, 1]. IFT-A polymerises interacts with IFT-B, and uses an array of beta-propeller and TPR domains to create 'carriages' of the IFT train that engage TULP adaptor proteins
[1]. The β-propeller domains of IFT140 contact the β-propeller domains of IFT121 from the adjacent complex
[2].
