Predicted to enable clathrin heavy chain binding activity and peptide binding activity. Predicted to be involved in clathrin coat assembly and clathrin-dependent endocytosis. Located in ciliary membrane and trans-Golgi network. Is expressed in central nervous system; dorsal root ganglion; liver; and neural retina. Orthologous to human CLTB (clathrin light chain B).
