Rabbit Anti-Aquaporin 2/FITC Conjugated antibody
background:
This gene encodes a water channel protein located in the kidney collecting tubule. It belongs to the MIP/aquaporin family, some members of which are clustered together on chromosome 12q13. Mutations in this gene have been linked to autosomal dominant, and recessive forms of nephrogenic diabetes insipidus.
Function:
Forms a water-specific channel that provides the plasma membranes of renal collecting duct with high permeability to water, thereby permitting water to move in the direction of an osmotic gradient.
Subcellular Location:
Apical cell membrane. Cytoplasmic vesicle membrane. Shuttles from vesicles to the apical membrane.
Tissue Specificity:
Expressed in renal collecting tubules.
Post-translational modifications:
Ser-256 phosphorylation is necessary and sufficient for expression at the apical membrane. Endocytosis is not phosphorylation-dependent.
DISEASE:
Defects in AQP2 are the cause of diabetes insipidus nephrogenic autosomal (ANDI) [MIM:125800]; also known as diabetes insipidus nephrogenic type 2. ANDI is caused by the inability of the renal collecting ducts to absorb water in response to arginine vasopressin. It is characterized by excessive water drinking (polydypsia), excessive urine excretion (polyuria), persistent hypotonic urine, and hypokalemia. Inheritance can be autosomal dominant or recessive.
Similarity:
Belongs to the MIP/aquaporin (TC 1.A.8) family.

通道蛋白(Channel Protein)
水通道蛋白-2特异地存在于肾脏集合管,受血管加压素调节。有研究证明,AQP2(水通道蛋白-2)在糖尿病肾脏集合管表达增强.
在1型糖尿病动物模型的水转运中尤其有意义。研究认为:AQP-2 奠定了糖尿病大鼠肾脏对水重吸收的基础,而且发现1型糖尿病病人的 AQP-2随血糖控制而减少。
