Lectin that binds to various sugars: galactose > mannose = fucose > N-acetylglucosamine > N-acetylgalactosamine. Acts as a chemoattractant, probably involved in the regulation of cell migration. Widely expressed. Highly expressed in lung. Weakly expressed in larynx, syrinx and cranial air sac. Expressed throughout the lower gastrointestinal tract in increasing levels starting from a faint signal in duodenum and ending with relatively high signals in proctodeum, coprodeum and urodeum. In the upper part of the gastrointestinal tract, expressed in tongue, crop, and mucosa of the crop. Belongs to the COLEC10/COLEC11 family.
