Anti-NSMCE4A / Non-SMC element 4 homolog A

Adding 0.2 ml of distilled water will yield a concentration of 500 ug/ml. NSMCE4A antibody detects Non-structural maintenance of chromosomes element 4A, a core component of the SMC5/6 complex involved in chromosome maintenance, DNA repair, and replication fork stability. Encoded by the NSMCE4A gene on chromosome 10q25.3, this protein forms part of the essential SMC5/6 complex that ensures proper segregation of sister chromatids and preserves genome integrity during cell division and stress. NSMCE4A serves as a bridging subunit, connecting the SMC5 and SMC6 heterodimer to regulatory and enzymatic cofactors that control DNA repair and replication restart.Structurally, NSMCE4A is a 34 kilodalton nuclear protein that interacts directly with SMC5 and SMC6 through its C-terminal coiled-coil domains, forming a stable hinge component of the complex. Its N-terminal region mediates associations with additional subunits such as NSMCE1 and NSMCE2, which confer ubiquitin ligase activity and DNA damage response signaling capacity. This modular organization enables NSMCE4A to coordinate complex assembly and spatial localization at damaged DNA sites.The NSMCE4A antibody is widely used in molecular biology, DNA repair, and cell cycle research to study chromosomal maintenance, recombination, and replication dynamics. Western blot analysis identifies a 34 kilodalton band corresponding to NSMCE4A, while immunofluorescence shows punctate nuclear staining that increases following DNA damage. This antibody provides a powerful reagent for investigating the SMC5/6 complex and its role in genome stability.Functionally, NSMCE4A is required for homologous recombination repair, resolution of DNA replication stress, and suppression of chromosomal rearrangements. Loss of NSMCE4A disrupts complex assembly, leading to DNA double-strand break accumulation and mitotic abnormalities. The SMC5/6 complex, including NSMCE4A, also regulates the maintenance of repetitive DNA sequences and prevents unscheduled recombination at telomeres and ribosomal DNA. Aberrant NSMCE4A expression or mutation has been implicated in genome instability disorders and cancer, where defective repair pathways promote genomic rearrangements. The NSMCE4A antibody enables sensitive detection and quantification of this repair factor in mechanistic studies of DNA integrity, replication stress, and chromosome segregation. NSJ Bioreagents validates this antibody for its applications, ensuring reproducible performance for DNA repair and chromosomal biology applications.
