Comments

Comment Type Description
Catalytic Activity 2 phenolic donor + H(2)O(2) = 2 phenoxyl radical of the donor + 2 H(2)O.
Cofactor Name=heme b; Xref=ChEBI:CHEBI:60344; Evidence= ; Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per heterodimer. ;
Developmental Stage Expressed both maternally and zygotically.
Disruption Phenotype Females are sterile, and maturing follicles show defects in actin filament formation, nurse cell membrane stability and border cell migration.
Function Required for ovarian follicle maturation. Involved in the formation of a rigid and insoluble egg chorion by catalyzing chorion protein cross-linking through dityrosine formation and phenol oxidase-catalyzed chorion melanization.
Sequence Caution Sequence=AAF78217.1; Type=Erroneous termination; Positions=810; Note=Translated as stop.; Evidence= ; Sequence=AAF78217.1; Type=Frameshift; Positions=220, 233, 238, 244, 331, 336, 381, 384, 644, 688; Evidence= ;
Similarity Belongs to the peroxidase family. XPO subfamily.
Subcellular Location Secreted . Note=In the chorion layer of the mature eggs.
Subunit Heterodimer.
Tissue Specificity Expressed at low levels in the germarium and early follicles. Expression becomes progressively stronger during vitellogenesis, and is highly expressed in germ cells and somatic cells. A subset of follicle cells, termed border cells (BC), exhibit a high level of expression.
