Blocking peptides are peptides that bind specifically to the target antibody and block antibody binding. These peptide usually contains the epitope recognized by the antibody. Antibodies bound to the blocking peptide no longer bind to the epitope on the target protein. By comparing the staining from the blocked antibody versus the antibody alone, one can see which staining is specific.

Research Backgrounds

P41181_AQP2_HUMAN

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. Plays an essential role in renal water homeostasis.

PTMs:

Ser-256 phosphorylation is necessary and sufficient for expression at the apical membrane. Endocytosis is not phosphorylation-dependent.

N-glycosylated.

Subcellular Location:

Apical cell membrane>Multi-pass membrane protein. Basolateral cell membrane>Multi-pass membrane protein. Cell membrane>Multi-pass membrane protein. Cytoplasmic vesicle membrane>Multi-pass membrane protein. Golgi apparatus>trans-Golgi network membrane>Multi-pass membrane protein.
Note: Shuttles from vesicles to the apical membrane (PubMed:15509592). Vasopressin-regulated phosphorylation is required for translocation to the apical cell membrane (PubMed:15509592). PLEKHA8/FAPP2 is required to transport AQP2 from the TGN to sites where AQP2 is phosphorylated (By similarity).

Tissue Specificity:

Expressed in collecting tubules in kidney medulla (at protein level). Detected in kidney.

Subunit Structure:

Homotetramer.

Family&Domains:

Aquaporins contain two tandem repeats each containing three membrane-spanning domains and a pore-forming loop with the signature motif Asn-Pro-Ala (NPA).

Belongs to the MIP/aquaporin (TC 1.A.8) family.

Research Fields

· Organismal Systems > Excretory system > Vasopressin-regulated water reabsorption.
