CC -!- FUNCTION: Functions in the lectin pathway of complement, which performs
CC a key role in innate immunity by recognizing pathogens through patterns
CC of sugar moieties and neutralizing them. The lectin pathway is
CC triggered upon binding of mannan-binding lectin (MBL) and ficolins to
CC sugar moieties which leads to activation of the associated proteases
CC MASP1 and MASP2. Functions as an endopeptidase and may activate MASP2
CC or C2 or directly activate C3 the key component of complement reaction.
CC Isoform 2 may have an inhibitory effect on the activation of the lectin
CC pathway of complement or may cleave IGFBP5. Also plays a role in
CC development. {ECO:0000250|UniProtKB:P48740}.
CC -!- ACTIVITY REGULATION: Inhibited by SERPING1 and A2M. {ECO:0000250}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=13 uM for C2 (at 37 degrees Celsius)
CC {ECO:0000269|PubMed:15060079};
CC -!- SUBUNIT: Homodimer. Interacts with the oligomeric lectins MBL2, FCN2
CC and FCN3; triggers the lectin pathway of complement through activation
CC of C3. Interacts with SERPING1. Interacts with COLEC11; probably
CC triggers the lectin pathway of complement.
CC {ECO:0000250|UniProtKB:P48740}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:12847554}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=3;
CC Name=1; Synonyms=MASP-1;
CC IsoId=Q8CHN8-1; Sequence=Displayed;
CC Name=2; Synonyms=MASP-3;
CC IsoId=Q8CHN8-2; Sequence=VSP_036818, VSP_036819;
CC Name=3;
CC IsoId=Q8CHN8-3; Sequence=VSP_036816, VSP_036817;
CC -!- TISSUE SPECIFICITY: Protein of the plasma which is primarily expressed
CC by liver. {ECO:0000269|PubMed:12847554}.
CC -!- PTM: The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate
CC and asparagine is (R) stereospecific within EGF domains. {ECO:0000250}.
CC -!- PTM: N-glycosylated. Some N-linked glycan are of the complex-type.
CC {ECO:0000269|PubMed:10913141}.
CC -!- PTM: Autoproteolytic processing of the proenzyme produces the active
CC enzyme composed on the heavy and the light chain held together by a
CC disulfide bond. Isoform 1 but not isoform 2 is activated through
CC autoproteolytic processing (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the peptidase S1 family. {ECO:0000255|PROSITE-
CC ProRule:PRU00274}.
