NEK11 Antibody / Serine/threonine-protein kinase Nek11

NEK11 antibody detects Serine/threonine-protein kinase Nek11, a member of the NIMA-related kinase family that regulates DNA damage checkpoints and cell cycle progression. The UniProt recommended name is Serine/threonine-protein kinase Nek11 (NEK11). This kinase functions downstream of ATM/ATR signaling pathways and mediates G2/M checkpoint arrest following genotoxic stress to allow DNA repair before mitosis.

Functionally, NEK11 antibody identifies a 645-amino-acid nuclear and cytoplasmic protein that becomes activated through phosphorylation in response to DNA damage. NEK11 phosphorylates and promotes the degradation of CDC25A phosphatase, inhibiting activation of CDK1-cyclin B and preventing premature entry into mitosis. By coupling checkpoint signaling to cell cycle control, NEK11 preserves genomic stability during replication stress and DNA repair. It also interacts with other checkpoint kinases such as CHK1 and PLK1, forming a regulatory network that ensures proper mitotic timing.

The NEK11 gene is located on chromosome 3q22.1 and is expressed in proliferative tissues including testis, thymus, and intestinal epithelium. Expression levels are highest in S and G2 phases, consistent with its role in cell cycle regulation. NEK11 activity integrates stress signals with checkpoint arrest and recovery mechanisms.

Pathologically, loss or mutation of NEK11 leads to genomic instability, defective DNA repair, and tumorigenesis. Downregulation is observed in colorectal, liver, and lung cancers, where impaired checkpoint function contributes to uncontrolled proliferation. Conversely, elevated NEK11 expression may sensitize tumor cells to genotoxic therapy by prolonging checkpoint arrest. Research using NEK11 antibody supports studies in DNA damage response, checkpoint regulation, and cancer biology.

NEK11 antibody is validated for western blotting, immunofluorescence, and immunohistochemistry to detect checkpoint kinases. NSJ Bioreagents provides NEK11 antibody reagents optimized for studies in genome integrity, DNA repair, and cell cycle control.

Structurally, Serine/threonine-protein kinase Nek11 contains an N-terminal catalytic kinase domain with a conserved lysine essential for ATP binding and a C-terminal regulatory region mediating protein-protein interactions. Its activation loop undergoes autophosphorylation to enhance catalytic activity following DNA damage. This antibody enables analysis of NEK11's role in coordinating checkpoint signaling and maintaining genomic stability.
