Protein attributes
| Sequence length | 1456 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Mediates the endocytosis of glycoproteins by macrophages. Binds both sulfated and non-sulfated polysaccharide chains. Acts as phagocytic receptor for bacteria, fungi and other pathogens. |
| Subcellular location | Endosome membrane; Single-pass type I membrane protein. Cell membrane; Single-pass type I membrane protein Ref.10. |
| Polymorphism | Genetic variations in MRC1 may influence susceptibility or resistance to leprosy in some populations. Particularly, Gly-396 seems to be a risk factor for leprosy when associated with Ala-399 and Phe-407. |
| Miscellaneous | CRDs 1-3 have at most very weak affinity for carbohydrate. CRD 4 shows the highest affinity binding and has multispecificity for a variety of monosaccharides. At least 3 CRDs (4, 5, and 7) are required for high affinity binding and endocytosis of multivalent glycoconjugates. |
| Sequence similarities | Contains 8 C-type lectin domains. Contains 1 fibronectin type-II domain. Contains 1 ricin B-type lectin domain. |
| Sequence caution | The sequence CAH70733.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAH70872.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAH71176.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI15339.1 differs from that shown. Reason: Erroneous gene model prediction. |
