CC -!- FUNCTION: Maintains epithelial barrier function by recruiting
CC MARVELD2/tricellulin to tricellular tight junctions (tTJs)
CC (PubMed:23239027). Crucial for normal hearing by maintaining the
CC structural and functional integrity of tTJs, which are critical for the
CC survival of auditory neurosensory HCs. Mediates fatty acids and
CC lipoproteins-stimulated CCK/cholecystokinin secretion in the small
CC intestine. In the inner ear, may regulate alternative pre-mRNA splicing
CC via binding to TRA2A, TRA2B and SRSF1 (By similarity).
CC {ECO:0000250|UniProtKB:Q8CBR1, ECO:0000269|PubMed:23239027}.
CC -!- SUBUNIT: Homooligomer (PubMed:15381095). Interacts with MARVELD2 and
CC OCLN; the interaction is required to recruit MARVELD2 to tricellular
CC contacts (PubMed:23239027). Interacts (via C-terminus) with TRA2A,
CC TRA2B and SRSF1 (By similarity). {ECO:0000250|UniProtKB:Q8CBR1,
CC ECO:0000269|PubMed:15381095, ECO:0000269|PubMed:23239027}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:15381095};
CC Single-pass type I membrane protein {ECO:0000269|PubMed:15381095}. Cell
CC junction, tight junction {ECO:0000269|PubMed:23239027}.
CC -!- SUBCELLULAR LOCATION: [Isoform 5]: Cytoplasm, cytosol
CC {ECO:0000269|PubMed:15381095}.

CC -!- TISSUE SPECIFICITY: Mainly expressed in prostate and to a lower extent
CC in testis, pancreas, kidney, heart and liver.
CC {ECO:0000269|PubMed:15381095}.
CC -!- DISEASE: Deafness, autosomal recessive, 42 (DFNB42) [MIM:609646]: A
CC prelingual, non-progressive form of non-syndromic sensorineural hearing
CC loss. Sensorineural deafness results from damage to the neural
CC receptors of the inner ear, the nerve pathways to the brain, or the
CC area of the brain that receives sound information.
CC {ECO:0000269|PubMed:21255762, ECO:0000269|PubMed:23239027}. Note=The
CC disease is caused by variants affecting the gene represented in this
CC entry.
CC -!- SIMILARITY: Belongs to the immunoglobulin superfamily. LISCH7 family.
CC {ECO:0000305}.
