DDX17 (p72/p82) was first detected as a bunyavirus inhibitor. Subsequent characterization revealed that it is an ATP-dependent RNA helicase, belonging to the DEAD-box group of proteins and bearing the signature Asp-Glu-Ala-Asp sequence. The presence of a novel upstream CTG translation start site (in addition to a conventional ATG start site) produces two isoforms: p72 is […]
DDX6 (RCK/p54) was first isolated from the RC-K8 B-cell lymphoma line over 30 years ago. This 472 amino acid, 53.2 kDa “DEAD-Box” ATP-dependent RNA helicase bears the signature Asp-Glu-Ala-Asp motif, characteristic of all DEAD box proteins. Dead box proteins contain both ATPase and helicase activity, and are known for their particular protein-protein and RNA-protein interactions […]
DDX5 (Dead-Box 5 or p68) is a member of a family of 37 “DEAD-Box” ATP-dependent RNA helicases that play a role in nearly all aspects of RNA processing and also act as nucleic acid recognition receptors for viral immunity. Dysregulation and/or overexpression of DDX5 can lead to tumor progression. It can also be hijacked by […]
Interested in DNA damage repair pathways for drug discovery? Join us for a live webinar, where Ha Pham, senior scientist at BellBrook Labs, will be sharing her expertise on using the Transcreener ADPR Assay, a biochemical HTS assay, to study enzymes involved in DNA damage repair. She will use CD38 and PARG as target examples […]
Researchers at the University of Tubingen use Transcreener to uncover how residence time works on a molecular level with p38α MAPK Inhibitors – Many factors affect the effectiveness of ligand-substrate or drug-target interactions. Conformational docking and stearic considerations help inform optimal “fits.” Ligand moiety solubility, both in free and bound forms, is also a consideration […]
DDX1 (Dead-Box Helicase 1) belongs to the DEAD-Box family of ATP-dependent RNA helicases, whose members are collectively involved in almost all aspects of RNA processing: from transcription to remodeling to degradation. They are named for the central Asp-Glu-Ala-Asp (DEAD) sequence they all possess. The 35 human DEAD-Box proteins comprise the largest family of helicases known. […]
RAB2 is part of the RAB family of small GTPases that regulate intracellular trafficking of membrane bound vesicles. It is highly conserved in eukaryotes, from C. elegans to humans. These GTPases influence the creation, movement, attachment, fusion, and destiny of vesicles originating in the endoplasmic reticulum (ER)/Golgi systems. Like other members of its family, RAB2 […]
Nearly a half-century ago, sequences from the Rous Sarcoma Virus were used to identify the first proto-oncogene and the first of a family of non-receptor tyrosine kinases: c-SRC. Unlike its viral counterpart (v-SRC), c-SRC exists in both an active and inactive state. It is produced in almost every cell type, but expressed highest in the […]
Bruton’s Tyrosine Kinase (BTK) is a 76kDa non-receptor Tec kinase that plays numerous diverse roles in B-cell development, immunity, autoimmunity, infection, and cancer. From stem to stern, it consists of an N-terminal plekstrin homology (PH) domain, a TEC homology (TH) domain, two SRC homology (SH2 and SH3) domains, and a C-terminal kinase domain. Unlike SRC, […]
SARM1 [Sterile alpha & toll/interleukin receptor (TIR) motif-containing protein 1] consists of a N-terminal mitochondrial localization sequence (NLS), an autoinhibitory HEAT/armadillo (ARM) domain, two tandem sterile alpha motif domains (SAMs), and a C-terminal toll/interleukin receptor domain (TIR). It is a human toll like receptor (TLR) adaptor protein. TLR adaptors (MYD88, MAL, TRIF, & TRAM) usually […]
