| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Amidohydrolase that hydrolyzes specifically one of the carboamide linkages in D-pantetheine thus recycling pantothenic acid (vitamin B5) and releasing cysteamine. Involved in the thymus homing of bone marrow cells. May regulate beta-2 integrin-mediated cell adhesion, migration and motility of neutrophil. Ref.9 |
| Catalytic activity | (R)-pantetheine + H2O = (R)-pantothenate + 2-aminoethanethiol. |
| Subcellular location | Cell membrane; Lipid-anchor › GPI-anchor Potential. |
| Tissue specificity | widely expressed with higher expression in spleen and blood. Ref.11 |
| Sequence similarities | Belongs to the CN hydrolase family. BTD/VNN subfamily. Contains 1 CN hydrolase domain. |

Alternative products
| This entry describes 5 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: O95498-1) 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: O95498-2) Also known as: GPI-80 variant protein 3; The sequence of this isoform differs from the canonical sequence as follows: 180-400: Missing. | ||||||
| Isoform 3 (identifier: O95498-3) Also known as: GPI-80 variant protein 2; The sequence of this isoform differs from the canonical sequence as follows: 180-192: YHLYSEPQFNVPE → ETLQSVKRSFAVI 193-520: Missing. | ||||||
| Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. | ||||||
| Isoform 4 (identifier: O95498-4) Also known as: GPI-80 variant protein 1; The sequence of this isoform differs from the canonical sequence as follows: 180-195: YHLYSEPQFNVPEKPE → EVVFMHQMVPKCIIMT 196-520: Missing. | ||||||
| Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. | ||||||
| Isoform 5 (identifier: O95498-5) Also known as: GPI-80 variant protein 4; The sequence of this isoform differs from the canonical sequence as follows: 116-119: FGHT → SAQC 120-520: Missing. | ||||||
| Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. |
