Phospho-PINK1 (Ser228) (E9K3K) Rabbit mAb

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). 1.Liu, W. et al.
