<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>

Adapter protein that plays a central role in localization of transcripts in the oocyte and in young embryos (PubMed:9118812).

Maintains RNA targets in a repressed state by promoting their deadenylation and protects deadenylated mRNAs from further degradation (PubMed:21937713).

Binds to and recruits eIF-4E to the 3'-UTR of some mRNA targets which prevents interaction between eIF4E1 and eIF4G (PubMed:14685270, PubMed:15465908, PubMed:21081899).

This may contribute to translational repression but does not appear to be necessary for it to occur (PubMed:21081899).

Can promote translational repression independently of deadenylation and eIF4E1 binding (PubMed:21937713).

Required for correct localization of eIF4E1 in the developing oocyte (PubMed:15465908).

Required for translational repression of oskar (osk) mRNA (PubMed:14691132, PubMed:14723848).

Also required for the translational repression of nanos (nos) mRNA (PubMed:21081899).

Promotes the accumulation of the germ plasm components osk, vas and stau at the posterior pole of the oocyte and is required for germ cell development (PubMed:22454519, PubMed:17277377).

Represses orb positive autoregulatory activity which prevents premature activation of orb and ensures its accumulation specifically in the developing oocyte (PubMed:22164257).

In 0-1 hour embryos, forms a complex with me31B, cup, tral and pAbp which binds to various mRNAs including maternal mRNAs, and down-regulates their expression during the maternal-to-zygotic transition (PubMed:28875934).

Predominantly expressed in ovaries and in 0-2 hours old embryos. Weakly expressed in testis. Expressed in young embryos through stage 9, then it decreases throughout the rest of embryogenesis. In ovaries, it is expressed in germ cells throughout pre-vitellogenic development, but is not expressed in the somatic follicle cells. In germarial cysts, the protein (and not the transcripts) is transported selectively into the oocyte.1 Publication

Expressed in the egg chamber and more specifically in nurse cells (at protein level) (PubMed:17277377). Expressed during the first 2 hours of embryogenesis but is absent in 2-5 hour embryos (at protein level) (PubMed:28875934). Expressed both maternally and zygotically (PubMed:9118812). Expressed throughout embryogenesis (PubMed:22454519). In stage 2, uniformly distributed throughout the whole embryo (PubMed:22454519). During blastoderm formation, concentrated at the posterior pole to become incorporated into newly formed germ cells (PubMed:22454519). Subsequently accumulates specifically in the pole cells at stage 10, when they migrate through the posterior midgut primordium, and during stage 14, when the germ cells reach their final destination (PubMed:22454519).2 Publications

No interaction was detected with pAbp in 1-5 hour embryos (PubMed:28875934).

Interacts with osk and vas (PubMed:22454519).

Interacts with Pop2, twin/CCR4, Rga, Not3 and Not1 which are all core components of the CCR4-NOT deadenylase complex; interaction with the complex is required for cup deadenylation activity (PubMed:21937713).

Annotation score:2 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>
