CC   -!- FUNCTION: Part of intraflagellar transport (IFT) particles involved in
CC       ciliary process assembly (PubMed:17604723). May play a role in the
CC       trafficking of ciliary membrane proteins from the Golgi complex to the
CC       cilium (PubMed:16775004). Regulates the platelet-derived growth factor
CC       receptor-alpha (PDGFRA) signaling pathway. Required for protein
CC       stability of E3 ubiquitin ligases CBL and CBLB that mediate
CC       ubiquitination and internalization of PDGFRA for proper feedback
CC       inhibition of PDGFRA signaling (PubMed:29237719). Essential for male
CC       fertility. Plays an important role in spermatogenesis, particularly
CC       spermiogenesis, when germ cells form flagella. May play a role in the
CC       transport of flagellar proteins ODF2 and SPAG16 to build sperm flagella
CC       and in the removal of redundant sperm cytoplasm (By similarity). Also
CC       involved in autophagy since it is required for trafficking of ATG16L
CC       and the expansion of the autophagic compartment (By similarity).

CC       IFT81, and IFT88. Interacts directly with IFT57 and KIF3B/Kinesin II
CC       subunit (By similarity). Interacts with IFT88 (By similarity).
CC       Interacts with CEP83 (PubMed:23530209). Interacts with SPEF2 (via C-
