Switch of PMCA4 splice variants in bovine epididymis results in altered isoform expression during functional sperm maturation.
results indicate possible functional compartmentalization of PMCA in bull sperm membranes and point to a presumptive, interaction partner of Ca(2+)-ATPase and PDC-109.
thermodynamic analysis of mitochondrial F1 ATPase (show DNAH8 ELISA Kits)
the ATP2B4 enhancer mediates red blood cell hydration and malaria susceptibility
Increased plasma membrane abundance of PMCA4b in vemurafenib-treated BRAF (show BRAF ELISA Kits) mutant cells is associated with enhanced Ca2 (show CA2 ELISA Kits)+ clearance.
The role of heterozygous variants of ATP2B4 is regulated by HSPG2 (show HSPG2 ELISA Kits) protein with transcription factors in bone formation through modulation of calcium signaling.
RNA sequencing identified a novel ATPase (show DNAH8 ELISA Kits), Ca2 (show CA2 ELISA Kits)+ transporting, plasma membrane 4(ATP2B4)-protein kinase C-alpha (PRKCA (show PKCa ELISA Kits)) fusion transcript.
our data show that CD147 interacts via its immunomodulatory domains with PMCA4 to bypass TCR proximal signaling and inhibit IL-2 (show IL2 ELISA Kits) expression.
We also nominate a new candidate gene in congenital arrhythmia, ATP2B4, and provide experimental evidence of a regulatory role for variants discovered using this framework.
p.R268Q mutation in PMCA4 resulted in functional changes in calcium homeostasis in human neuronal cells. This suggests that calcium dysregulation may be associated with the pathogenesis of Familial spastic paraplegia
The slowly activating PMCA4b isoform produced long-lasting Ca2 (show CA2 ELISA Kits)+ oscillations in response to store-operated Ca2 (show CA2 ELISA Kits)+ entry.
While PMCA1b (show ATP2B1 ELISA Kits) has a housekeeping function in colon cancer cells, PMCA4b participates in the reorganization of the calcium signaling machinery during cell differentiation.
Mechanism of PMCA4 that creates lipid asymmetry is well understood in terms of ATP hydrolysis; molecular models exist for trajectory taken by phospholipid substrates through the enzyme. [review-like article]
PMCA4 co-ordinates both Ca2 (show CA2 ELISA Kits)+ and NO signaling in mammalian sperm, to control sperm motility.
PMCA4 has no discernible role in normal renal Ca2 (show CA2 ELISA Kits)+ handling as no urinary Ca2 (show CA2 ELISA Kits)+ wasting was observed. Further investigation of the exact role of PMCA4 in the distal convoluted tubule and connecting tubule is required
PMCA4 regulates the development of cardiac hypertrophy and provide proof of principle for a therapeutic approach to treat this condition.
Electron microscopy demonstrated Pmca4 localization in distal nephron cells at both the basolateral membrane and intracellular perinuclear compartments but not submembranous vesicles
Findings indicate an important regulation of plasma membrane Ca(2+)-ATPase (show ATP2B2 ELISA Kits) (PMCA) by Homer2 (show HOMER2 ELISA Kits) protein that has a central role on PMCA-mediated Ca(2 (show CA2 ELISA Kits)+) signaling in parotid acinar cells.
PMCA4 inhibits the activation of the calcineurin/NFAT pathway on VEGF stimulation of endothelial cells, leading to a significant attenuation of VEGF-mediated angiogenesis.
this study concludes that Ca(2 (show CA2 ELISA Kits)+) efflux activity of PMCA4 underlies G1 progression in vascular smooth muscle cells and that PMCA4a and PMCA4b differentially regulate specific downstream mediators.
Ca(2 (show CA2 ELISA Kits)+) homeostasis in sperm is maintained by the relative ratios of CASK (show CASK ELISA Kits)-PMCA4b and CASK (show CASK ELISA Kits)-JAM-A (show F11R ELISA Kits) interactions
Plasma membrane calcium pump (show ATP2B2 ELISA Kits) (PMCA) isoform 4 is targeted to the apical membrane by the w-splice insert from PMCA2 (show ATP2B2 ELISA Kits).
The protein encoded by this gene belongs to the family of P-type primary ion transport ATPases characterized by the formation of an aspartyl phosphate intermediate during the reaction cycle. These enzymes remove bivalent calcium ions from eukaryotic cells against very large concentration gradients and play a critical role in intracellular calcium homeostasis. The mammalian plasma membrane calcium ATPase isoforms are encoded by at least four separate genes and the diversity of these enzymes is further increased by alternative splicing of transcripts. The expression of different isoforms and splice variants is regulated in a developmental, tissue- and cell type-specific manner, suggesting that these pumps are functionally adapted to the physiological needs of particular cells and tissues. This gene encodes the plasma membrane calcium ATPase isoform 4. Alternatively spliced transcript variants encoding different isoforms have been identified.
