NPSR1
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]
Full Name
Neuropeptide S Receptor 1
Function
G-protein coupled receptor for neuropeptide S (NPS) (PubMed:16790440).
Promotes mobilization of intracellular Ca2+ stores (PubMed:16790440).
Inhibits cell growth in response to NPS binding (PubMed:15947423).
Involved in pathogenesis of asthma and other IgE-mediated diseases.

Asthma-related traits 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.
