Genes affected

OPRD1 (HGNC:8153): (opioid receptor delta 1) Enables G protein-coupled enkephalin receptor activity. Involved in several processes, including G protein-coupled opioid receptor signaling pathway; cellular response to hypoxia; and positive regulation of peptidyl-serine phosphorylation. Is intrinsic component of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]
