Applications for PINK1 Antibody - BSA Free

Application
Recommended Usage

Simple Western

1:50

Western Blot

1:100-1:2000
Application Notes
Western blot - Use at 1:500 to 1:1,000 dilution. This antibody has only been tested on transfected lysates. Endogenous protein detection is unknown. No other applications have been tested.

In Simple Western only 10 - 15 uL of the recommended dilution is used per data point. Separated by Size-Wes, Sally Sue/Peggy Sue.
The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors. Unprocessed PINK1 is 63 kDa which undergoes proteolytic processing to generate 55 kDa and 42 kDa cleaved forms, and bands at the mentioned positions may be expected in Western blot application.
Please Note: Optimal dilutions of this antibody should be experimentally determined.

Background: PINK1

Phosphatase and Tensin Homolog (PTEN) is a tumor suppressor which acts as an antagonist to phosphatidylinositol 3-kinase (PI3K) signaling. PTEN exerts enzymatic activity as a phosphatidylinositol-3,4,5-trisphosphate (PIP3) phosphatase, opposing PI3K activity by reducing availability of PIP3 to proliferating cells. Loss of PTEN function leads to elevated PIP3 and increased activation of PI3K/AKT signaling in many types of cancer.

PINK1 (PTEN induced putative kinase 1) protein contains a N-terminal mitochondrial targeting sequence, putative transmembrane helix, linker region, serine (Ser65)/threonine (Thr257) kinase domain and C-terminal segment. PINK1 is translated in the cytosol, then translocated to the outer mitochondrial membrane where it is rapidly cleaved and degraded as a part of normal mitochondrial function. In damaged (depolarized) mitochondria, PINK1 becomes stabilized and accumulates, resulting in the subsequent phosphorylation of numerous proteins on the mitochondrial surface.

When PINK1 is imported into the cell, mitochondrial processing peptidase, presenilin-associated rhomboid-like protease and AFG3L2 cleave PINK1 and tag it for the ubiquitin-proteasome pathway, keeping low PINK1 protein expression at basal conditions (1,2). Accumulation of PINK1 in mitochondria indicate damage. PINK1 maintains mitochondrial function/integrity, provides protection against mitochondrial dysfunction during cellular stress, and is involved in the clearance of damaged mitochondria via selective autophagy (mitophagy) (3). PINK1 has a theoretical molecular weight of 63 kDa and undergoes proteolytic processing to generate at least two cleaved forms (55 kDa and 42 kDa).

Ultimately PARK2 (E3 Ubiquitin Ligase Parkin) is recruited to the damaged mitochondria where it is activated by 1) PINK-mediated phosphorylation of PARK2 at serine 65, and 2) PARK2 interaction with phosphorylated ubiquitin (also phosphorylated by PINK1 on serine 65) (4,5). There is a strong interplay between Parkin and PINK1, where loss-of-function of human PINK1 results in mitochondrial pathology and can be rescued by Parkin (2,4,5). Mutations in either Parkin or PINK1 alter mitochondrial turnover, resulting in the accumulation of defective mitochondria and, ultimately, neurodegeneration in Parkinson's disease. Mutations in the PINK1 gene located within the PARK6 locus on chromosome 1p35-p36 have been identified in patients with early-onset Parkinson's disease (6).
