Subcellular locations: Membrane
Co-localizes with crystalloid granules of eosinophils and granular organelles of mast cells, neutrophils, macrophages and dendritic cells.
Expressed in gastrointestinal and immune tissue, as well as prostate, testis and ovary. Expressed in lamina propria and eosinophils but not in epithelial cells. Expression is greater in benign adjacent tissues than in colon tumors.
