The antiserum was produced against synthesized peptide derived from human DNA-PK around the phosphorylation site of Ser2056.

General description

Protein kinase, DNA-activated, catalytic polypeptide (PRKDC), also known as DNAPK, is encoded by the gene mapped to human chromosome 8q11. PRKDC is characterized by a large catalytic polypeptide and DNA-binding component comprised of the Ku70 and Ku80 heterodimer, that targets DNA-PKc, to DNA.

Physical form

Rabbit IgG in phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.


Anti-phospho-DNA-PK (pSer2056) antibody produced in rabbit has been used in immunofluorescence analysis.

Biochem/physiol Actions

Protein kinase, DNA-activated, catalytic polypeptide (PRKDC), also known as DNAPK, plays an essential role in the colorectal cancer (CRC) cell proliferation/survival. Therefore, it can be used as a potential prognostic biomarker and a therapeutic target for CRC. Decreased expression of PRKDC influences apoptosis partially by inhibiting AKT activation. Overexpression of activated DNAPK elevates the expression of rearranged during transfection (RET), which is a proto-oncogene involved in the development of medullary thyroid cancer (MTC). DNAPK plays a crucial role in non-homology end joining (NHEJ) pathway. Downregulation of DNAPK enhances anticancer drug induced DNA damage repair in osteosarcoma cell line MG63.
