Antigène: POLM (Polymerase (DNA Directed), mu (POLM))

Autre désignation: POLM

Sujet: POLM antibody detects DNA polymerase mu, a specialized DNA polymerase involved in non-homologous end joining (NHEJ) and DNA repair. The UniProt recommended name is DNA polymerase mu (POLM). This enzyme belongs to the X family of DNA polymerases, functioning at sites of double-strand breaks to fill in short gaps and process damaged DNA ends during repair.

Functionally, POLM antibody identifies a 494-amino-acid nuclear enzyme that exhibits template-dependent and template-independent polymerase activities. POLM incorporates nucleotides opposite damaged or missing bases, ensuring ligation competency of DNA ends. Unlike high-fidelity polymerases, POLM lacks strong proofreading activity, allowing it to tolerate mismatched or gapped templates-a property critical for repair flexibility in NHEJ.

The POLM gene is located on chromosome 7p13 and is expressed in immune and proliferative tissues such as thymus and bone marrow. It plays a key role in V(D)J recombination and class switch recombination in lymphocytes by repairing programmed double-strand breaks. Its activity complements DNA polymerase lambda (POLL) in filling in short DNA overhangs during repair.

Pathologically, dysregulation of POLM contributes to genomic instability and may influence cancer development, immune function, and cellular aging. Overexpression can increase mutation rates, whereas deficiency impairs NHEJ efficiency. POLM's balance between flexibility and error rate is vital for maintaining genome integrity while allowing adaptability in immune diversification.

POLM antibody is validated for western blotting, immunofluorescence, and immunohistochemistry to detect DNA polymerase mu in nuclear extracts. NSJ Bioreagents provides POLM antibody reagents optimized for DNA repair, recombination, and genomic maintenance research.

Structurally, DNA polymerase mu contains an N-terminal BRCT domain mediating protein-protein interactions, followed by a catalytic polymerase domain with palm, fingers, and thumb subdomains typical of X-family enzymes. This antibody supports studies on POLM's mechanistic role in end joining, mutation repair, and adaptive immunity.
