| Protein names | Recommended name: Peroxidasin EC=1.11.1.7 | ||||
| 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 | 1527 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Plays a role in extracellular matrix consolidation, phagocytosis and defense. Ref.1 |
| Catalytic activity | 2 phenolic donor + H2O2 = 2 phenoxyl radical of the donor + 2 H2O. |
| Cofactor | Binds 1 calcium ion per subunit By similarity. Binds 1 heme B (iron-protoporphyrin IX) group covalently per subunit By similarity. |
| Subunit structure | Homotrimer; disulfide-linked. Ref.1 |
| Subcellular location | Secreted Potential. |
| Tissue specificity | Expressed in hemocytes. Also expressed in the fat body and gastric caeca. Ref.1 |
| Developmental stage | Expressed throughout embryonic and larval development. Expressed in hemocytes as they migrate in the early embryo and later in embryogenesis, become localized to basement membranes. Ref.1 |
| Sequence similarities | Belongs to the peroxidase family. XPO subfamily. Contains 4 Ig-like C2-type (immunoglobulin-like) domains. Contains 5 LRR (leucine-rich) repeats. Contains 1 LRRCT domain. Contains 1 LRRNT domain. Contains 1 VWFC domain. |
| Sequence caution | The sequence AAA61568.1 differs from that shown. Reason: Frameshift at several positions. |
Ontologies
Alternative products
| This entry describes 2 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform A (identifier: Q9VZZ4-1) Also known as: C; D; E; 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: Q9VZZ4-2) The sequence of this isoform differs from the canonical sequence as follows: 456-457: EL → GE 458-1527: Missing. | ||||||
| Note: No experimental confirmation available. |
