Product Information

Product Usage Information

Application Dilution
Western Blotting 1:1000

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

Phospho-PINK1 (Ser228) (E9K3K) Rabbit mAb recognizes transfected levels of PINK1 protein only when phosphorylated at Ser228. Non-specific bands of unknown origin are observed migrating at ~32 kDa, and at ~80 kDa in mouse cell lines. Human species reactivity is weak by western blot.

Species Reactivity:

Mouse

Species predicted to react based on 100% sequence homology

Human

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser228 of human PINK1 protein.

Background

PTEN induced putative kinase 1, PINK1, is a mitochondrial serine/threonine kinase involved in the normal function and integrity of mitochondria, as well as in reduction of cytochrome c release from mitochondria (1-3). PINK1 phosphorylates Parkin and promotes its translocation to mitochondria (2). Research studies have shown that mutations in PINK1 are linked to autosomal recessive early onset Parkinson’s disease, and are associated with loss of protective function, mitochondrial dysfunction, aggregation of α-synuclein, as well as proteasome dysfunction (1,3).

It has been shown that autophosphorylation of PINK1 at Ser228 and Ser402 is necessary for Parkin recruitment to damaged mitochondria (4).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
