General Notes
This product (Catalog No. DPABH-21608) is a rabbit-derived polyclonal antibody raised against human CARM1. This antibody exhibits cross-reactivity with Human CARM1 from mouse, rat, and monkey. It has been affinity purified by Protein A. CARM1, also named as PRMT4, belongs to the protein arginine N-methyltransferase family. It is a dual functional coregulator that facilitates transcription initiation by methylation of Arg17 and Arg26 of histone H3 and also dictates the subsequent coactivator complex disassembly by methylation of the steroid receptor coactivator family coactivators and p300/cAMP-response element-binding protein. CARM1 functions as a coactivator for many nuclear receptors, such as oestrogen receptor, androgen receptor, thyroid receptor and farnesoid X-receptor. It also coactivates other transcription factors such as myocyte enhancer factor 2C (MEF2C), β-catenin, p53, nuclear factor (NF)-kB and the cAMP-responsive element-binding factor. The enzymatic activity and coactivator function of CARM1 has been found to be inactivated through phosphorylation at a conserved serine residue at mitosis stage.
DPABH-21608 is suitable for use in IHC (1:50–1:500), IF/ICC (1:20–1:200) applications.
DPABH-21608 is supplied as a liquid formulation in PBS with 0.02% sodium azide and 50% glycerol, pH 7.3. For long-term storage, keep at −20 °C. For short-term use, store at 2–8 °C. Avoid repeated freeze–thaw cycles to maintain antibody integrity and performance.
