General annotation (Comments)
| Function | T-cell surface glycoprotein CD1e, soluble is required for the presentation of glycolipid antigens on the cell surface. The membrane-associated form is not active. Ref.2 Ref.10 |
| Subunit structure | Heterodimer with B2M (beta-2-microglobulin). The association with B2M appears to be facilitated by the presence of the propeptide. |
| Subcellular location | T-cell surface glycoprotein CD1e, membrane-associated: Golgi apparatus membrane; Single-pass type I membrane protein. Early endosome. Late endosome. Note: Predominantly localized in the trans-Golgi network in immature dendritic cells, and as a cleaved, soluble protein in the lysosome lumen of mature dendritic cells. Ref.2 Ref.11 Ref.12 T-cell surface glycoprotein CD1e, soluble: Lysosome lumen. |
| Tissue specificity | Expressed on cortical thymocytes, dendritic cells, Langerhans cells, on certain T-cell leukemias, and in various other tissues. Ref.2 |
| Post-translational modification | Mono-ubiquitinated. Proteolytically cleaved in late endosomes to yield a soluble form. Ref.2 Ref.11 Ref.12 |
| Polymorphism | Six alleles of CD1E are known. CD1E*01 has His-102/Glu-106/Ser-149/Arg-164/Leu-194, CD1E*02 has His-102/Arg-106/Ser-149/Arg-164/Leu-194, CD1E*03 (9L) has His-102/Glu-106/Ser-149/Trp-164/Leu-194, CD1E*04 (15L) has His-102/Glu-106/Ser-149/Arg-164/Pro-194, CD1E*05 has Arg-102/Arg-106/Ser-149/Arg-164/Leu-194 and CD1E*06 has His-102/Arg-106/Asn-149/Arg-164/Leu-194. The sequence shown is that of allele CD1E*01. |
| Sequence similarities | Contains 1 Ig-like (immunoglobulin-like) domain. |
| Sequence caution | The sequence CAA33100.1 differs from that shown. Reason: Erroneous gene model prediction. |
