Introduction of ATP11B
ATP11B is encoded by ATP11B gene. It belongs to P4-ATPases family, which can preferentially translocate phosphatidylserine of cell membrane. It commonly exists in several tissues, such as neural stem cells, kidney, testis, as well as ovary. Meanwhile, some studies conducted on ATP11B suggest that it is related to many diseases, like ovarian cancer.

Function of ATP11B Membrane Protein
ATP11B is a member of P-type ATPases family, which is phosphorylated in their intermediate state and drives uphill transport of ions across membranes. It plays a critical role in many cellular processes associated with the plasma membrane and intracellular membranes. Previous studies indicate that most mammalian ATP11B use CDC50A as their β-subunit. Researches show it is highly expressed on kidney, ovary, which indicate that it may associated with these tissues-related diseases. Moreover, it may be a potential biomarker in clinical therapy.

Application of ATP11B Membrane Protein in Literature
This article reports that the effects of ATP11B on the morphology change of neural stem cells by using RNAi. These data strongly suggest that ATP11B plays a key role in the morphological change of neural stem cells.
This article reveals that the expression level of ATP11B is possibly related with higher tumor grade in human ovarian cancer samples and with cisplatin resistance in human ovarian cancer cell lines.
Authors in this group analyze the gene expression profile of 39 ABC and 12 SLC transporters and three ATPases (ATP7A, ATP7B and ATP11B) in epithelial ovarian cancer tissues and address their putative role in prognosis and clinical course of epithelial ovarian cancer patients.
This article conducts an ATP11B reanalysis assay, including DNA sequencing, sequence comparisons and analysis using PCR. The results illustrate that the transmembrane domain 4 (exon 12) can be identified not only in human ATP11B, but also in a number of animal species, such as rabbits and mice, which indicates that ATP11B may play a critical role in encoding the RING finger-binding protein.
Authors in this group analyze three deletions (SOX2, FXR1 and ATP11B) to map possible breakpoints on the homologous bovine chromosome. The data indicates that three bovine BAC clones targeting BTA1q33 have been developed for further eye malformation research in cattle.
