Protein attributes
| Sequence length | 922 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Involved in inositol deacylation of GPI-anchored proteins. GPI inositol deacylation may important for efficient transport of GPI-anchored proteins from the endoplasmic reticulum to the Golgi By similarity. |
| Subcellular location | Endoplasmic reticulum membrane; Multi-pass membrane protein By similarity. |
| Sequence similarities | Belongs to the GPI inositol-deacylase family. |
| Sequence caution | The sequence AAQ88987.1 differs from that shown. Reason: Erroneous initiation. The sequence BC040517 differs from that shown. Reason: Frameshift at position 333. |
Ontologies
Alternative products
| This entry describes 4 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q75T13-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: Q75T13-2) The sequence of this isoform differs from the canonical sequence as follows: 1-174: Missing. | ||||||
| Note: No experimental confirmation available. | ||||||
| Isoform 3 (identifier: Q75T13-3) The sequence of this isoform differs from the canonical sequence as follows: 592-592: R → A 593-922: Missing. | ||||||
| Note: No experimental confirmation available. | ||||||
| Isoform 4 (identifier: Q75T13-4) The sequence of this isoform differs from the canonical sequence as follows: 50-269: Missing. 652-922: Missing. | ||||||
| Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. No experimental confirmation available. |
