The EPN motif is essential for recognition of the peptidoglycan carbohydrate backbone and for efficient bacterial killing with Glu-114 playing a key role in peptidoglycan binding and bactericidal activity.
Bactericidal C-type lectin which acts against several intestinal Gram-positive and Gram-negative bacteria. Lacks antibacterial activity against S.typhimurium. May play a role in protection against infection with S.enteritidis by inhibiting its translocation from the gut lumen into intestinal tissues and further extraintestinal tissues.
Acts as a hormone in response to different stimuli. Secreted by different cell types to activate its receptor EXTL3 and induce cell specific signaling pathways (PubMed:34099862). In pancreas, is able stimulate cell proliferation (PubMed:34099862).
Overexpressed during the acute phase of pancreatitis.
Proteolytic processing by trypsin removes an inhibitory N-terminal propeptide and is essential for peptidoglycan binding and antibacterial activity.
Constitutively expressed in the small intestine, moderately in colon and at an extremely low level in healthy pancreas.
