Predicted to enable microtubule binding activity and protein homodimerization activity. Predicted to be involved in several processes, including detection of light stimulus involved in visual perception; regulation of protein localization to cilium; and retina homeostasis. Predicted to act upstream of or within post-embryonic retina morphogenesis in camera-type eye and retinal rod cell development. Predicted to be located in several cellular components, including Flemming body; cytosol; and microtubule organizing center. Predicted to be active in cilium; microtubule; and photoreceptor inner segment. Orthologous to human CCDC66 (coiled-coil domain containing 66). [provided by Alliance of Genome Resources, Apr 2022]
