Probable metal transporter. The interaction with the metal ion chaperone COX11 suggests that it may play a role in sensory neuron functions (By similarity). May play a role in biomineralization and retinal function. Interacts with COX11. Widely expressed. Highly expressed in heart. The disease is caused by variants affecting the gene represented in this entry. Shares weak sequence similarity with the cyclin family, explaining its name. However, it has no cyclin-like function in vivo. Belongs to the ACDP family. Truncated N-terminus. Truncated N-terminus.
