<unk> s (collagen-containing C-type lectins) are a part of the innate immune system. They form a family of collagenous Ca2+-dependent defense lectins, which are found in animals.<unk> s are soluble pattern recognition receptors (PRRs). Their function is to bind to oligosaccharide structure or lipids which are on the surface of microorganisms. Like other PRRs they bind pathogen-associated molecular patterns (PAMPs) and also danger-associated molecular patterns (DAMPs) of oligosaccharide origin. Binding of<unk> s to microorganisms may trigger elimination of microorganisms by aggregation[disambiguation needed], complement activation, opsonization, activation of phagocytosis or  inhibition of microbial growth. Other functions of<unk> s are modulation of inflammatory, allergic responses, adaptive immune system and clearance of apoptotic cells.
