Descrição geral

Aquaporin 2 (AQP2) exists as a tetramer with C terminus showing multiple conformations and binds two cadmium ions. AQP2 gene is mapped to human chromosome 12q13.12. It is associated with intracellular vesicles.
Aquaporin 2 (AQP2) is a water channel protein that regulates water balance in renal connecting tubules and collecting ducts. AQP2 is activated by anti-diuretic hormone and subsequently facilitates water inflow in renal cells. This protein also interacts with integrin to modulate epithelial cell morphogenesis and cell movement . Anti-Water Channel Aquaporin 2 antibody recognizes aquaporin 2 from rat by immunoblotting. The antibody also reacts with mouse and human AQP2.

Imunogênio

synthetic peptide corresponding to amino acids 254-271 of rat or mouse aquaporin 2 (with additional N-terminal lysine and tyrosine) conjugated to KLH with glutaraldehyde. The epitope is identical in rat and mouse and highly conserved in human.

Aplicação

Anti-Water Channel Aquaporin 2 antibody is also suitable for use in chemiluminescent western blot (1:200-1:1000), and immunoblot.
Anti-Water Channel Aquaporin 2 antibody produced in rabbit has been used in:
  • immunostaining
  • immunohistochemistry
  • immunofluorescence
  • immunoblotting

Immunohistochemistry was performed on 10% formalin-fixed parraffin embedded rat kidney sections using rabbit anti-AQP2 at a concentration of 5μg/ml. Use of anti-AQP2 allowed visualization of the medullary thick ascending limb and collecting ducts.

Ações bioquímicas/fisiológicas

Aquaporin (AQP2) N-terminal region plays a key role in trafficking. The C-terminal phosphorylation is crucial for the water permeability function of the apical membrane. Also, ubiquitination at lysine 270 is needed for AQP2 sorting and degradation in lysosomes or elimination through exosomes. Mutation in AQP2 gene is implicated in congenital nephrogenic diabetes insipidus (NDI), a water balance disorder. The functional dysregulation of AQP2 is also correlated to preeclampsia, congestive heart failure and liver cirrhosis.

forma física
