NPSR1 Antibody – Rabbit Polyclonal

This gene encodes a member of the vasopressin/oxytocin subfamily of G protein-coupled receptors. The encoded membrane protein acts as a receptor for neuropeptide S and affects a variety of cellular processes through its signaling. Increased expression of this gene in ciliated cells of the respiratory epithelium and in bronchial smooth muscle cells is associated with asthma. Polymorphisms in this gene have also been associated with asthma susceptibility, panic disorders, inflammatory bowel disease, and rheumatoid arthritis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

NPSR1: May be active in signaling pathway in an autocrine or paracrine fashion in several tissues. Receptor for neuropeptide S, it may mediate its action, such as inhibitory effects, on cell growth. Involved in pathogenesis of asthma and other IgE-mediated diseases. Defects in NPSR1 are a cause of asthma-related traits type 2 (ASRT2). Asthma-related traits include clinical symptoms of asthma, such as coughing, wheezing, dyspnea, bronchial hyperresponsiveness as assessed by methacholine challenge test, serum IgE levels, atopy and atopic dermatitis. Belongs to the G-protein coupled receptor 1 family. Vasopressin/oxytocin receptor subfamily. 9 isoforms of the human protein are produced by alternative splicing.
