Biological Context

Subcellular Location: Cell membrane (Single-pass type I membrane protein); Cell projection, microvillus; Secreted
Tissue Specificity: Detected in fibroblasts and urine (at protein level). Detected in placenta (at protein level). Isoform 10 (epithelial isoform) is expressed by cells of epithelium and highly expressed by carcinomas. Expression is repressed in neuroblastoma cells
