Descriptions Names[Advanced Search]

Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). Combining with an opsonin to initiate a change in cell activity. The selective, non-covalent, often stoichiometric, interaction of a molecule with one or more specific sites on another molecule. Interacting selectively and non-covalently with the C1q component of the classical complement cascade. Interacting selectively and non-covalently with a collectin, a member of a group of structurally related pattern recognition molecules characterized by having a carbohydrate recognition domain of the C-type lectin family at the C-terminus and a collagenous domain at the N-terminus. Interacting selectively and non-covalently with a pentraxin, a member of a family of inflammatory proteins with a radially symmetric arrangement of five identical, noncovalently linked chains in a pentagonal array. Interacting selectively and non-covalently with the C4b product of the classical complement cascade. Interacting selectively and non-covalently with an opsonin, such as a complement component or antibody, deposited on the surface of a bacteria, virus, immune complex, or other particulate material. Interacting selectively and non-covalently with the iC3b product of the complement cascade. Interacting selectively and non-covalently with the C3b product of the complement cascade.
