NSP16 Shows Promise for Anti-Viral Therapeutics

Tuesday, 20 September 2022 by Bellbrook Labs
NSP16 Target for COVID-19 Therapeutics
SARS-CoV-2 virus (Covid-19) possesses one of the largest genomes of any RNA virus. While it naturally encodes structural proteins among its 29 genes, it also produces non-structural proteins that are necessary to perpetuate infection. Non-structural protein 16 (NSP16) is one such protein.1 NSP16 Camouflages Viral mRNA NSP16 is an m7GpppA-specific, S-adenosyl-L-methionine-dependent 2’-O-methyltransferase (2’-O-MTase) that “caps”

PRMT5 is Innately Interesting

Wednesday, 30 March 2022 by Bellbrook Labs
PRMT5 Role with Macrophages
PRMT5 is a type II arginine methyltransferase that dimethylates arginine residues symmetrically. Its various functions extend into T cell development, B cell regulation, hematopoiesis, and mitotic control. In the past, research on PRMT5 primarily focused on cancer and the adaptive immune response. These are both situations where metabolism and growth are critical. Recent reports implicate

The Contribution of DNA Methyltransferase Inhibitors in Treating Myelodysplastic Syndromes

Tuesday, 01 October 2019 by Bellbrook Labs
DNA Methyltransferase Inhibitors for MDS
Myelodysplastic syndromes (MDS) are a broad, complex group of cancers characterized by the inability to form mature, healthy blood cells. There are different types with varying degrees of risk associated, making it difficult to diagnose and treat. Additionally, many patients are symptom-free and at an older age where they are likely to have other life-threatening

How a Methyltransferase Activity Assay Could Help Identify Novel Breast Cancer Treatments

Monday, 22 April 2019 by Bellbrook Labs
Pink Stethascope DOT1L Breast Cancer Target 420 X 280
As estrogen receptor (ER) positive breast cancer (BC) becomes resistant to antiestrogen therapy, novel ways to control the disease are and continue to be developed. There are different types of breast cancer, and the most effective treatment depends on knowing this difference.  For example, if the type is estrogen receptor positive (ER) meaning cells are

Sensitive Methyltransferase Assay Proves Successful with PRMT4

Thursday, 11 October 2018 by Bellbrook Labs
Histone Methylation PRMT4
Histone methyltransferases (HMTs) play a critical role in many diseases. Dysregulation of histone methylation and the subsequent alterations in epigenetic states can cause gene expression patterns that drive a variety of cancers,[1] endometriosis,[2] osteoporosis,[3] osteoarthritis and rheumatoid arthritis,[4] cardiovascular disease,[5] and autism,[6] to name only a few. In this light, a global assay for HMT

A Novel Approach Discovers Hundreds of Cancer-Relevant Arginine Methylation Sites for CARM1

Thursday, 14 December 2017 by Bellbrook Labs
Protein arginine methylation is an important post-translational modification, but its impact remains rather mysterious. Approximately 7% of all arginine residues in the human proteome are modified by mono- or di-methylation (which is a similar order of magnitude to the 9% of serine residues that are phosphorylated and the 7% of lysine residues that are ubiquitinated).¹

Previously Recorded Webinar – The New AptaFluor™ SAH Methyltransferase Assay: A Homogenous, Universal Assay Based on a Microbial Riboswitch

Monday, 31 July 2017 by Bellbrook Labs
Epigenetic regulation has been shown to be a contributing factor in a variety of diseases, and discovery of methyltransferase inhibitors is an area of intense activity. Methyltransferase enzymes methylate a variety of substrates using S-adenosylmethionine (SAM) as the methyl donor leaving S-adenosylhomocysteine (SAH) as a common product. Since the difference between SAH and SAM is
