The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:

"
Mannose-Binding Protein A, subunit A

FunFam 155: Serum lectin isoform 1

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 5 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Chitin binding GO:0008061
Interacting selectively and non-covalently with chitin, a linear polysaccharide consisting of beta-(1->4)-linked N-acetyl-D-glucosamine residues.
2 A0A060WRB3 (/IDA) P81018 (/IDA)
Calcium ion binding GO:0005509
Interacting selectively and non-covalently with calcium ions (Ca2+).
1 Q800Z5 (/IDA)
Mannose binding GO:0005537
Interacting selectively and non-covalently with mannose, a monosaccharide hexose, stereoisomeric with glucose, that occurs naturally only in polymerized forms called mannans.
1 Q800Z5 (/IDA)
Identical protein binding GO:0042802
Interacting selectively and non-covalently with an identical protein or proteins.
1 Q800Z5 (/IDA)
Mannan binding GO:2001065
Interacting selectively and non-covalently with mannan.
1 Q800Z5 (/IDA)

There are 4 GO terms relating to "biological process"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Respiratory burst involved in defense response GO:0002679
A phase of elevated metabolic activity, during which oxygen consumption increases made as part of a defense response ; this leads to the production, by an NADH dependent system, of hydrogen peroxide (H2O2), superoxide anions and hydroxyl radicals.
1 Q800Z5 (/IDA)
Phagocytosis, engulfment GO:0006911
The internalization of bacteria, immune complexes and other particulate matter or of an apoptotic cell by phagocytosis, including the membrane and cytoskeletal processes required, which involves one of three mechanisms: zippering of pseudopods around a target via repeated receptor-ligand interactions, sinking of the target directly into plasma membrane of the phagocytosing cell, or induced uptake via an enhanced membrane ruffling of the phagocytosing cell similar to macropinocytosis.
1 Q800Z5 (/IDA)
Opsonization GO:0008228
The process in which a microorganism (or other particulate material) is rendered more susceptible to phagocytosis by coating with an opsonin, a blood serum protein such as a complement component or antibody.
1 Q800Z5 (/IDA)
Protein homooligomerization GO:0051260
The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of identical component monomers. Oligomers may be formed by the polymerization of a number of monomers or the depolymerization of a large protein polymer.
1 Q800Z5 (/IDA)

There are 6 GO terms relating to "cellular component"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Extracellular space GO:0005615
That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
3 A0A060WRB3 (/IDA) P81018 (/IDA) Q800Z5 (/IDA)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
2 A0A060WRB3 (/IDA) P81018 (/IDA)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
1 P81018 (/IDA)
Plasma membrane GO:0005886
The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
1 P81018 (/IDA)
Brush border GO:0005903
The dense covering of microvilli on the apical surface of a epithelial cells in tissues such as the intestine, kidney, and choroid plexus; the microvilli aid absorption by increasing the surface area of the cell.
1 P81018 (/IDA)
Cytolytic granule GO:0044194
A specialized secretory lysosome that is present in cells with cytolytic capability such as cytotoxic T lymphocytes and natural killer cells. Cytolytic granules mediate the storage and regulated excretion of lytic molecules for killing of target cells.
