Function
Zebrafish CaMK-II is expressed in ciliated tissues including Kupffer's vesicle (PMID 20630945), kidney (PMID 21752935), neuromasts and inner ear, and its suppression alters ciliated hair-cell number and Delta-Notch signalling. The zebrafish work does not resolve which human CAMK2 paralog is responsible; no CAMK2B-specific ciliary localization has been curated.
