Primarily expressed in the digestive tract, mainly in colon. Detected in smaller amounts in brain, urogenital organs, testis, and salivary and mammary glands. Highly expressed in the epithelial layer and submucosal gland of the inferior turbinate mucosa. Lower levels in the epithelial layer of nasal polyp.
Cell membrane; Single-pass membrane protein. Apical cell membrane. Secreted. The C-terminus 30 kDa form is anchored to the membrane. The N-terminus 110 kDa form is released from the membrane triggered by an unknown stimulus.
