Description

PRMT1 (Protein Arginine N-Methyltransferase 1) serves as the predominant type I arginine methyltransferase in mammalian cells, catalyzing the asymmetric dimethylation of arginine residues on histones and numerous non-histone substrates. This enzyme plays essential roles in transcriptional regulation, RNA processing, DNA damage response, and signal transduction pathways. Dysregulation of PRMT1 activity has been implicated in various cancers and inflammatory conditions, making it a compelling target for researchers investigating epigenetic mechanisms and potential therapeutic interventions.

This recombinant monoclonal antibody, generated in rabbit using clone 4D10, offers the reproducibility and consistency that demanding experimental workflows require. Because recombinant antibodies are produced from defined sequences rather than traditional hybridoma methods, researchers benefit from lot-to-lot uniformity that supports longitudinal studies and ensures comparable results across experiments.

Validation across multiple platforms demonstrates this antibody's versatility in diverse experimental contexts. Western blot analysis confirms specific detection of PRMT1 at the expected 42 kDa molecular weight across human cell lines including HEK293, SH-SY5Y, and Jurkat, as well as mouse NIH/3T3 cells, supporting the stated cross-species reactivity with human and mouse samples. Immunohistochemistry staining in paraffin-embedded human colorectal cancer tissue reveals clear target localization, while immunofluorescence studies in HeLa cells and flow cytometry analysis in HepG2 cells further confirm reliable performance in cell-based applications.

The unconjugated format provides flexibility for pairing with detection systems of your choice. Whether investigating PRMT1's role in chromatin remodeling, characterizing methylation-dependent protein interactions, or exploring its involvement in disease pathology, this antibody delivers the specificity and cross-platform compatibility essential for rigorous epigenetic research.

Target Background

Function

Arginine methyltransferase that methylates (mono and asymmetric dimethylation) the guanidino nitrogens of arginyl residues present in proteins such as ESR1, histone H2, H3 and H4, ILF3, HNRNPA1, HNRNPD, NFATC2IP, SUPT5H, TAF15, EWS, HABP4 and SERBP1. Constitutes the main enzyme that mediates monomethylation and asymmetric dimethylation of histone H4 'Arg-4' (H4R3me1 and H4R3me2a, respectively), a specific tag for epigenetic transcriptional activation. May be involved in the regulation of TAF15 transcriptional activity, act as an activator of estrogen receptor (ER)-mediated transactivation, play a key role in neurite outgrowth and act as a negative regulator of megakaryocytic differentiation, by modulating p38 MAPK pathway. Methylates RBM15, promoting ubiquitination and degradation of RBM15. Methylates FOXO1 and retains it in the nucleus increasing its transcriptional activity. Methylates CHTOP and this methylation is critical for its 5-hydroxymethylcytosine (5hmC)-binding activity. Methylates H4R3 in genes involved in glioblastomagenesis in a CHTOP- and/or TET1-dependent manner. Plays a role in regulating alternative splicing in the heart.
