Genes affected
GPR39 (HGNC:4496): (G protein-coupled receptor 39) This gene is a member of the ghrelin receptor family and encodes a rhodopsin-type G-protein-coupled receptor (GPCR). The encoded protein is involved in zinc-dependent signaling in epithelial tissue in intestines, prostate and salivary glands. The protein may also be involved in the pathophysiology of depression. [provided by RefSeq, Jun 2016]
LYPD1 (HGNC:28431): (LY6/PLAUR domain containing 1) Predicted to enable acetylcholine receptor binding activity and acetylcholine receptor inhibitor activity. Predicted to be involved in acetylcholine receptor signaling pathway. Predicted to act upstream of or within several processes, including behavioral fear response; cholinergic synaptic transmission; and negative regulation of protein localization to plasma membrane. Predicted to be located in membrane. [provided by Alliance of Genome Resources, Apr 2022]
