CC   -!- FUNCTION: Calcium-dependent lectin involved in innate immune defense.
CC       Binds mannose, fucose and N-acetylglucosamine on different
CC       microorganisms and activates the lectin complement pathway. Binds to
CC       late apoptotic cells, as well as to apoptotic blebs and to necrotic
CC       cells, but not to early apoptotic cells, facilitating their uptake by
CC       macrophages (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Oligomeric complex of 3 or more homotrimers. Interacts with
CC       MASP1 and MASP2 (By similarity). Interacts with MEP1A and MEP1B and may
CC       inhibit their catalytic activity (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- DOMAIN: The coiled-coil domain mediates trimerization. {ECO:0000250}.
CC   -!- PTM: Hydroxylation on proline residues within the sequence motif, GXPG,
CC       is most likely to be 4-hydroxy as this fits the requirement for 4-
CC       hydroxylation in vertebrates. {ECO:0000250}.
