FunFam 10: Erythrocyte binding antigen-181

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 2 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
Heparin binding GO:0008201
Interacting selectively and non-covalently with heparin, any member of a group of glycosaminoglycans found mainly as an intracellular component of mast cells and which consist predominantly of alternating alpha-(1->4)-linked D-galactose and N-acetyl-D-glucosamine-6-sulfate residues.
 2 Q8I2B4 (/IDA) Q8I2B4 (/IDA)
Sialic acid binding GO:0033691
Interacting selectively and non-covalently with sialic acid, any of a variety of N- or O- substituted derivatives of neuraminic acid, a nine carbon monosaccharide. Sialic acids often occur in polysaccharides, glycoproteins, and glycolipids in animals and bacteria.

GO Term Annotations Evidence
Entry into host cell GO:0030260
The invasion by an organism of a cell of its host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction.
 2 Q8I2B4 (/IDA) Q8I2B4 (/IDA)
Cell-cell adhesion GO:0098609
The attachment of one cell to another cell via adhesion molecules.

There are 1 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
Microneme GO:0020009
A small, elongated secretory organelle that forms part of the apical complex, located along the main axis of an apicomplexan parasite cell within the extreme apical region and at the periphery under the inner membrane complex. Of the specialized secretory compartments identified in apicomplexans, micronemes discharge their contents first, during initial contact of the parasite's apical pole with the host cell surface. Micronemal proteins function during parasite attachment and penetration into the target cell.
