We report here a novel family of G-protein coupled receptor (GPCR) which is extraordinarily conserved among vertebrate species. This family, designated SREB (Super Conserved Receptor Expressed in Brain), consists of at least three members, termed SREB1, SREB2, and SREB3. SREB members share 52-63% amino acid identity with each other and show relatively high similarity to previously known amine amine GPCRs (approximately 25% identity). Amino acid sequence identity between human and rat… 

Characterization of the G protein-coupled receptor family SREB across fish evolution

Gonadal patterns suggested an important role for all sreb genes in teleost testicular development, while gar were characterized by greater ovarian expression that may reflect similar roles to mammals.

Identification and molecular docking studies for novel inverse agonists of SREB, super conserved receptor expressed in brain

An in vitro screening of 5472 chemical compounds from the RIKEN NPDepo chemical library indicated that the SREB family could couple Gs‐type G proteins, and S REB–Gsα fusion proteins showed significant constitutive activities.

The evolutionarily conserved G protein-coupled receptor SREB2/GPR85 influences brain size, behavior, and vulnerability to schizophrenia

It is shown that SREB2 is involved in determining brain size, modulating diverse behaviors, and potentially in vulnerability to schizophrenia, and its pathway as a target for psychiatric therapy.

Super-conserved receptors expressed in the brain: biology and medicinal chemistry efforts.

This review intends to provide a comprehensive overview of the SREB family and its recent advances in biology and medicinal chemistry.

Identification and relative quantitation of an orphan G-protein coupled receptor SREB2 (GPR85) protein in tissue using a linear ion trap mass spectrometer.

Mass spectrometric identification and relative quantitative analysis of SREB2 in the forebrains of transgenic and wild type mice using nanoliquid chromatography coupled with a linear ion-trap mass spectrometer are reported.

SREB 2 / GPR 85 , a schizophrenia risk factor , negatively regulates hippocampal adult neurogenesis and neurogenesis-dependent learning and memory

It is shown that SREB2 regulates hippocampal adult neurogenesis, which impacts on cognitive function, and inhibition of S REB2 function may be a novel approach to enhance hippocampusal adult Neurogenesis and cognitive abilities to ameliorate core symptoms of psychiatric patients.

Premetazoan Origin of Neuropeptide Signaling

It is revealed that secreted neuropeptide homologs derived from longer precursors have premetazoan origins and thus evolved before neurons, suggesting that prohormone processing occurs also in choanoflagellates.

Discovery of three novel G-protein-coupled receptor genes.

The molecular cloning, tissue distribution, and chromosomal localization of novel genes encoding G-protein-coupled receptors (GPCRs) are reported, and the gene encoding GPR30 was localized to chromosome 7p22 and GPR35 to chromosome 2q37.

Inactivation of a Novel Neuropeptide Y/Peptide YY Receptor Gene in Primate Species*

This novel NPY receptor represents the first neurotransmitter receptor identified that has universally lost its receptor function in primate species, and despite its inactivation in humans, the transcripts were abundantly detected in the heart and skeletal muscle, suggesting a novel function of the human gene.

The family of G‐protein‐coupled receptors

The family of G‐protein‐coupled receptors can be defined by their similar structural and functional characteristics. Although their primary sequences are quite diverse, these proteins share several

This review will examine current progress in addressing a fundamental question in the field of GPCR-mediated signal transduction: the nature of the physical changes in receptors that link agonist binding to G protein activation.

The pEFBOS vector will be used to produce a large amount of growth factors and proteins in mammalian cells, to express a high level of anti-sense RNA, and will be an ideal positive control for CAT assay in various cell types.

Cloning of the gene for a human dopamine D4 receptor with high affinity for the antipsychotic clozapine

The cloning of a gene that encodes a dopamine receptor gene that has high homology to the human dopamine D2 and D3 receptor genes is reported, which suggests the existence of other types of dopamine receptors which are more sensitive to clozapine.
