Predicted to enable identical protein binding activity. Predicted to be involved in bicellular tight junction assembly and calcium-independent cell-cell adhesion via plasma membrane cell-adhesion molecules. Predicted to act upstream of or within axon ensheathment and spermatogenesis. Predicted to be located in several cellular components, including lipid droplet; neurofilament; and tight junction. Predicted to be active in bicellular tight junction and plasma membrane. Human ortholog(s) of this gene implicated in hypomyelinating leukodystrophy. Orthologous to human CLDN11 (claudin 11).
