Predicted to be involved in bicellular tight junction assembly and establishment of endothelial barrier. Predicted to act upstream of or within cell-cell junction organization and sensory perception of sound. Predicted to be located in several cellular components, including Schmidt-Lanterman incisure; basolateral plasma membrane; and tight junction. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 49. Orthologous to human MARVELD2 (MARVEL domain containing 2).
