ChEMBL is an Open Data database containing binding, functional and ADMET information for a large number of drug-like bioactive compounds. These data are manually abstracted from the primary published literature on a regular basis, then further curated and standardized to maximize their quality and utility across a wide range of chemical biology and(More)
A novel human G protein-coupled receptor named AXOR12, exhibiting 81% homology to the rat orphan receptor GPR54, was cloned from a human brain cDNA library. Heterologous expression of AXOR12 in mammalian cells permitted the identification of three surrogate agonist peptides, all with a common C-terminal amidated motif. High potency agonism, indicative of a(More)
Erythroid Krüppel-like factor (EKLF) was originally isolated from erythroid cell RNA by differential screening and shown to be erythroid-specific, although a low level of EKLF was found in mast cell lines. EKLF contains three zinc-fingers homologous to those found in the Krüppel family of transcription factors. Because it binds the sequence CCACACCCT, EKLF(More)
Using a genomics-based reverse pharmacological approach for screening orphan G-protein coupled receptors, we have identified and cloned a novel high-affinity histamine receptor. This receptor, termed AXOR35, is most closely related to the H3 histamine receptor, sharing 37% protein sequence identity. A multiple responsive element/cyclic AMP-responsive(More)
We have identified a type I cytokine receptor, which we have termed novel interleukin receptor (NILR), that is most related to the IL-2 receptor beta chain (IL-2Rbeta) and physically adjacent to the IL-4 receptor alpha chain gene on chromosome 16. NILR mRNA is most highly expressed in thymus and spleen, and is induced by phytohemagglutinin in human(More)
BACKGROUND CatSper1 and CatSper2 are two recently identified channel-like proteins, which show sperm specific expression patterns. Through targeted mutagenesis in the mouse, CatSper1 has been shown to be required for fertility, sperm motility and for cAMP induced Ca2+ current in sperm. Both channels resemble a single pore forming repeat from a four repeat(More)
Astrocytes invade the developing retina from the optic nerve head, over the axons of retinal ganglion cells (RGCs). RGCs express the platelet-derived growth factor A-chain (PDGF-A) and retinal astrocytes the PDGF alpha-receptor (PDGFR alpha), suggesting that PDGF mediates a paracrine interaction between these cells. To test this, we inhibited PDGF signaling(More)
The process of learning involves stable changes in synaptic efficacy for which long-term potentiation (LTP) provides a widely adopted mammalian model. Synaptic modification induced by learning or LTP may involve the action of cell adhesion molecules. One such candidate is the ubiquitous neuronal glycoprotein Thy-1. In mice in which the gene encoding Thy-1(More)
Using homology searching of public databases with a metabotropic glutamate receptor sequence from Caenorhabditis elegans, two novel protein sequences (named RAIG-2 (HGMW-approved symbol GPRC5B) and RAIG-3 (HGMW-approved symbol GPRC5C) were identified containing seven putative transmembrane domains characteristic of G-protein-coupled receptors (GPCRs).(More)
