Also known as FLJ23499
Summary
CFAP68 (cilia and flagella associated protein 68, HGNC:1163) is a protein-coding gene on chromosome 11q23.1, encoding Cilia- and flagella-associated protein 68 (Q9H5F2). Microtubule inner protein (MIP) part of the dynein-decorated doublet microtubules (DMTs) in cilia axoneme, which is required for motile cilia beating.
Predicted to be involved in flagellated sperm motility. Located in axoneme and nucleoplasm.
