Tissue SpecificityWidely expressed with highest levels in adult brain, small intestine and lymphoid tissues such as thymus and spleen. Expression is frequently lower in intestinal-type gastric cancer. In obese patients, more abundant in omental than in subcutaneous fat. {ECO:0000269|PubMed:11350957, ECO:0000269|PubMed:12792799, ECO:0000269|PubMed:19805157}.
