Alpha-1B adrenergic receptor

Adrenoceptor alpha 1B
Identifiers
ADRA1B Gene
RNA expression pattern

The alpha-1B adrenergic receptor1B adrenoreceptor), also known as ADRA1B, is an alpha-1 adrenergic receptor, and also denotes the human gene encoding it.[1]

Receptor

There are 3 alpha-1 adrenergic receptor 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. They activate mitogenic responses and regulate growth and proliferation of many cells.

Gene

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.[1]

Interactions

Alpha-1B adrenergic receptor has been shown to interact with AP2M1.[2] A role in regulation of dopaminergic neurotransmission has also been suggested.[3][4]
