Product Specifications

Immunogen

Peptide sequence from Ubiquitin, phosphorylated at Serine 65.
Accession # P0CG47

Specificity

This antibody detects mono- and poly-Ubiquitin chains that are phosphorylated on Serine 65. It has no cross-reactivity with non-phosphorylated Ubiquitin, Ubiquitin phosphorylated at Serine 57 or Tyrosine 59, or phosphorylated Parkin. Detects only recombinant, phosporylated Ubiquitin. Not recommended on natural lysates (see western blot results below).

Detection of Phospho-Ubiquitin (S65) antibody by Western Blot.

Detection of Phospho-Ubiquitin (S65) by Western blot.

Tetraubiquitin chains of each indicated linkage type were incubated for 0-4 hours in reactions containing recombinant PINK1 kinase (Cat# AP-180) and ATP. At indicated times a portion of each reaction was removed and terminated with SDS-PAGE sample buffer. SDS-PAGE gels (10-20%) were used to resolve approximately 150 ng of Ubiquitin tetramer from each reaction. Western Blots were developed using either alpha-phospho-Ubiquitin, pS65 (upper panels) or anti-Ubiquitin (Cat# MAB701, lower panel). Primary antibodies were used at 1 μg/ml in PBST + 0.5% BSA, while HRP-labeled secondary antibodies ( alpha-rabbit for A-110, alpha-mouse for MAB701) were used at a 1:10,000 dilution in PBST + 0.5% BSA. Further details are available upon request.

Background: Ubiquitin

Serine/Threonine kinase PINK1 (PTEN-induced putative kinase protein 1) plays a critical role in preventing mitochondrial dysfunction during cellular stress. PINK 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 PINK becomes stabilized and accumulates, resulting in the subsequent phosphorylation of numerous proteins on the mitochondrial surface including Mfn2. Ultimately PARK2 (E3 Ubiquitin Ligase Parkin) is recruited to the damaged mitochondria where it is activated by PINK-mediated phosphorylation of PARK2 at serine 65, and PARK2 interaction with phosphorylated Ubiquitin (also phosphorylated by PINK on serine 65). This signaling cascade is critical for clearing the damaged mitochondria via selective autophagy (mitophagy) by mediating activation and translocation of PARK2.
