General description

Podocin is a podocyte structural protein, that belongs to the band-7-stomatin family of lipid raft-associated proteins. This family contains more than 1800 conserved proteins which share ∼150 amino acid domains showing similarity to mitochondrial protein prohibitin (PHB).
Podocin is a hairpin-like integral membrane protein with intracellular N- and C- termini. Podocin is located at the insertion site of the slit membrane, an intercellular junction found in mammalian kidney.

Specificity

Anti-Podocin recognizes human, mouse, and rat podocin.

Immunogen

Synthetic peptide corresponding to amino acid residues of human podocin with an N-terminal added cysteine, conjugated to KLH. The corresponding sequence is identical in mouse and differs by one amino acid in rat.

Application

Anti-Podocin antibody produced in rabbit has been used for Western Blotting and immunohistochemistry.

Biochem/physiol Actions

Podocin and nephrin are essential for maintaining the slit diaphragm. Studies show that mutations in this gene account for around 15% cases of nephrotic syndrome cases. Podocin interacts with cholesterol and promotes the formation of protein-lipid supercomplexes, which control ion channel complexes. The podocin gene is known to be associated with autosomal recessive SRNS (nephrotic syndrome type 2). Podocin actively participates in the ultrafiltration process occuring in kidney.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month.
For extended storage, freeze in working aliquots. Repeated freezing and thawing is not recommended. Storage in frost-free freezers is also not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.
