Protein attributes
| Sequence length | 1457 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at transcript level. |
General annotation (Comments)
| Function | Required for the maintenance of phospholipid turnover within the photoreceptor. Ref.1 |
| Catalytic activity | ATP + 1,2-diacylglycerol = ADP + 1,2-diacyl-sn-glycerol 3-phosphate. |
| Subcellular location | |
| Tissue specificity | Expressed specifically in adult eye. Ref.1 |
| Disruption phenotype | Flies exhibit photoreceptor cells that degenerate within a week after eclosion. Ref.1 |
| Sequence similarities | Belongs to the eukaryotic diacylglycerol kinase family. Contains 4 ANK repeats. Contains 1 DAGKc domain. Contains 2 phorbol-ester/DAG-type zinc fingers. |
| Sequence caution | The sequence AAQ22428.1 differs from that shown. Reason: Miscellaneous discrepancy. Intron retention. |
Ontologies
Alternative products
| This entry describes 3 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform A (identifier: Q09103-1) 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 B (identifier: Q09103-3) The sequence of this isoform differs from the canonical sequence as follows: 1-116: MQQQQQPSID...KQQSSSSASA → MPERSISQRD...EDIEMLDYDT 117-564: Missing. 1315-1315: S → SNKDRLFSFNEDVFGCGFS 1445-1457: KQGTQPVDGWLDD → QERFMHLEKQTRI | ||||||
| Note: No experimental confirmation available. | ||||||
| Isoform C (identifier: Q09103-2) The sequence of this isoform differs from the canonical sequence as follows: 1-132: MQQQQQPSID...AGFLQVPLAA → MERLLHAVRE...SLGAWRRKRR 133-565: Missing. | ||||||
| Note: No experimental confirmation available. |
