Function

TRadial spoke head protein 4 homolog A appears to be a component the radial spoke head, as determined by homology to similar proteins in the biflagellate alga Chlamydomonas reinhardtii and other ciliates. Radial spokes, which are regularly spaced along cilia, sperm, and flagella axonemes, consist of a thin 'stalk' and a bulbous 'head' that form a signal transduction scaffold between the central pair of microtubules and dynein.^[5]

Clinical significance

Mutations in the RSPH4A gene are associated with primary ciliary dyskinesia.^[6]
