Function

CCDC40 is required for assembly of motile cilia. It is responsible for CCDC39 axonemal recruitment. It is important for cytoplasmic pre- assembly, axonemal targeting, and/or transport of axonemal components CCDC39, GAS11 and D LI1. Necessary for assembly of inner dynein arms, the dynein regulatory complex and plays a role in the establishment of the left- right patterning (21131974). Cilia were shorter in Kupffer’s vesicle and the pronephric tubules of ccdc40 (PMID: 21131974)
