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. Combining with a pentraxin to initiate a change in cell activity. Combining with the iC3b product of the complement cascade to initiate a change in cell activity. Combining with the C1q component of the classical complement cascade to initiate a change in cell activity. Combining with the C4b product of the classical complement cascade to initiate a change in cell activity. Combining with an extracellular or intracellular messenger to initiate a change in cell activity. 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. Combining with a collectin to initiate a change in cell activity. Combining with the C5a product of the complement cascade to initiate a change in cell activity.
