Previous GeneCards Identifiers for ADRA1B Gene
Alpha-1-adrenergic receptors (alpha-1-ARs) are members of the G protein-coupled receptor superfamily. They activate mitogenic responses and regulate growth and proliferation of many cells. There are 3 alpha-1-AR subtypes: alpha-1A, -1B and -1D, all of which signal through the Gq/11 family of G-proteins and different subtypes show different patterns of activation. This gene encodes alpha-1B-adrenergic receptor, which induces neoplastic transformation when transfected into NIH 3T3 fibroblasts and other cell lines. Thus, this normal cellular gene is identified as a protooncogene. This gene comprises 2 exons and a single large intron of at least 20 kb that interrupts the coding region.

GeneCards Summary for ADRA1B Gene
ADRA1B (Adrenoceptor Alpha 1B) is a Protein Coding gene. Diseases associated with ADRA1B include ureterolithiasis. Among its related pathways are Signaling by GPCR and Activation of cAMP-Dependent PKA. GO annotations related to this gene include protein heterodimerization activity and alpha1-adrenergic receptor activity. An important paralog of this gene is HTR1F.
UniProtKB/Swiss-Prot for ADRA1B Gene
This alpha-adrenergic receptor mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system. Its effect is mediated by G(q) and G(11) proteins. Nuclear ADRA1A-ADRA1B heterooligomers regulate phenylephrine (PE)-stimulated ERK signaling in cardiac myocytes.
Adrenergic alpha1 receptors (alpha1-adrenoceptors) are members of the adrenergic receptor group of G-protein-coupled receptors that also includes alpha2A, alpha2B, alpha2C, beta1, beta2 and beta3. The adrenergic alpha1 receptors are further divided into three subtypes: alpha1A, alpha1B and alpha1D receptors. lpha1-adrenoceptors are widely distributed in both the CNS and periphery where they play a major role in smooth muscle contraction. A fourth alpha1 receptor subtype has been postulated and is designated as alpha1L based on its low affinity for prazosin. It has been suggested that this subtype may represent a different conformational state of the alpha1A subtype.
