Function

May be involved in cell migration and/or actin cytoskeleton organization. When expressed in keratinocytes, induces changes in cell morphology with transfected cells showing an elongated shape, numerous membrane protrusions, major reorganization of the actin cytoskeleton, increased motility and decreased cell adhesion. Required for normal lung cell proliferation and alveolus formation at birth. Induces platelet aggregation. Does not have any effect on folic acid or amino acid transport. Does not function as a water channel or as a regulator of aquaporin-type water channels. {ECO:0000250UniProtKB:Q62011, ECO:0000269PubMed:14522983, ECO:0000269PubMed:15231832, ECO:0000269PubMed:15515019, ECO:0000269PubMed:9651190}.

Disease Associations

Tissue Specificity

Highly expressed in placenta, lung, skeletal muscle and brain. Weakly expressed in brain, kidney and liver. In placenta, expressed on the apical plasma membrane of endothelium. In lung, expressed in alveolar epithelium. Up-regulated in colorectal tumors and expressed in 25% of early oral squamous cell carcinomas. {ECO:0000269PubMed:10393083, ECO:0000269PubMed:14522983, ECO:0000269PubMed:15515019}.
