PRG2 and AQPEP are misexpressed in fetal membranes in placenta previa and percretadagger.
Title: PRG2 and AQPEP are misexpressed in fetal membranes in placenta previa and percreta†.
Overexpression of LVRN impedes the invasion of trophoblasts by inhibiting epithelial-mesenchymal transition.
Title: Overexpression of LVRN impedes the invasion of trophoblasts by inhibiting epithelial-mesenchymal transition.
First trimester maternal serum laeverin level cannot be used to predict preeclampsia.
Title: Maternal serum laeverin (aminopeptidase Q) measured in the first trimester of pregnancy does not predict preeclampsia.
Laeverin is expressed in all trophoblast cell types of normal and preeclamptic placentas. Expression pattern of laeverin in trophoblast cells is heterogeneous and not necessarily membrane-bound.
Title: Laeverin protein expression in normal and preeclamptic placentas using tissue microarray analysis.
In preeclamptic placentas, laeverin is experssed in the cytoplasm and microvesicles, rather than the cell membrane. Laeverin appears to be involved in trophoblast cell migration and invasion through interaction with integrins and matrix metalloprotease 1.
Title: Placental expression of aminopeptidase-Q (laeverin) and its role in the pathophysiology of preeclampsia.
Laeverin is a specific cell-surface marker for human extravillous trophoblast (EVT) and plays a regulatory role in EVT migration.
Title: Laeverin/aminopeptidase Q induces trophoblast invasion during human early placentation.
Replacement of glutamine-238 with alanine caused a significant change in substrate specificity rather than a decrease in enzymatic activity.
Title: Involvement of glutamine-238 in the substrate specificity of human laeverin/aminopeptidase Q.
Clinical trial of gene-disease association and gene-environment interaction. (HuGE Navigator)
Title: Personalized smoking cessation: interactions between nicotine dose, dependence and quit-success genotype score.
These results indicate that His(379) of laeverin plays essential roles in its distinctive enzymatic properties and contributes to maintaining the appropriate structure of the catalytic cavity of the enzyme.
Title: Histidine 379 of human laeverin/aminopeptidase Q, a nonconserved residue within the exopeptidase motif, defines its distinctive enzymatic properties.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
