Product Overview
This rabbit polyclonal antibody recognizes protein arginine N-methyltransferase 5 (gene PRMT5) in human, mouse and rat samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 72.7 kDa, and the supplier reports an observed band at about 72 kDa.
PRMT5 is the principal type II protein arginine methyltransferase, forming symmetric dimethylarginine together with its partner WDR77 (MEP50). It methylates Sm proteins needed for spliceosomal snRNP assembly as well as histones and transcription factors, and it has become an important target in cancer research, particularly in MTAP-deleted tumors.

Immunogen
Recombinant human PRMT5 fragment (Ser16–Asp355), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places protein arginine N-methyltransferase 5 in the cytoplasm, nucleus, chromosome and Golgi apparatus. Tissue expression noted by UniProt (human): Ubiquitous. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
