| Protein names | Recommended name: Tyrosine-protein kinase Btk29A EC=2.7.10.2 Alternative name(s): Dsrc28C Dsrc29a | ||||||
| Gene names |
| ||||||
| Organism | Drosophila melanogaster (Fruit fly) [Reference proteome] | ||||||
| Taxonomic identifier | 7227 [NCBI] | ||||||
| Taxonomic lineage | Eukaryota › Metazoa › Ecdysozoa › Arthropoda › Hexapoda › Insecta › Pterygota › Neoptera › Endopterygota › Diptera › Brachycera › Muscomorpha › Ephydroidea › Drosophilidae › Drosophila › Sophophora › ![]() |
Protein attributes
| Sequence length | 786 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Required for proper ring canal development. Also required for the development of male genitalia and for adult survival. Ref.2 Ref.9 |
| Catalytic activity | ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. |
| Cofactor | Binds 1 zinc ion per subunit By similarity. |
| Subcellular location | Note: Ring canals. |
| Tissue specificity | Ring canals in the egg chambers and imaginal disks of third-instar larvae. Ref.1 Ref.2 Ref.9 |
| Developmental stage | Expressed both maternally and zygotically. Predominantly in early to middle embryogenesis, in larvae and adult females. Ref.1 Ref.2 |
| Disruption phenotype | Flies exhibit shortened copulatory duration (due to incomplete fusion of the left and right halves of the apodeme that holds the penis during copulation) and reduced adult-stage life span. Ref.2 |
| Sequence similarities | Belongs to the protein kinase superfamily. Tyr protein kinase family. TEC subfamily. Contains 1 Btk-type zinc finger. Contains 1 PH domain. Contains 1 protein kinase domain. Contains 1 SH2 domain. Contains 1 SH3 domain. |
| Sequence caution | The sequence AAA28912.1 differs from that shown. Reason: Frameshift at positions 62, 215, 218, 220 and 401. |
Ontologies
Alternative products
| This entry describes 2 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform B (identifier: P08630-1) Also known as: D; E; Type 2; 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 A (identifier: P08630-2) Also known as: C; F; Type 1; The sequence of this isoform differs from the canonical sequence as follows: 1-183: Missing. 184-231: EDSNTPKSYR...HWREANNNPS → MIPCVSLAET...SLTSSKTKEG |
