Predicted to enable sphingolipid binding activity. Predicted to be involved in negative regulation of apoptotic process. Predicted to act upstream of or within sphingolipid biosynthetic process. Predicted to be located in several cellular components, including nuclear lumen; photoreceptor inner segment; and photoreceptor outer segment. Human ortholog(s) of this gene implicated in retinitis pigmentosa and retinitis pigmentosa 26. Orthologous to human CERKL (ceramide kinase like). [provided by Alliance of Genome Resources, Apr 2022]
