PROKR2（prokineticin receptor 2），癌症关联基因，基因ID：128674，促激动素是一种分泌蛋白，能促进血管生成，诱导胃肠道平滑肌强烈收缩。该基因编码的蛋白是前激动素的膜蛋白和G蛋白偶联受体编码的蛋白在序列上与GPR73相似，GPR73是另一种G蛋白偶联的前激动剂受体[由RefSeq提供，2008年7月]Prokineticins are secreted proteins that can promote angiogenesis and induce strong gastrointestinal smooth muscle contraction. The protein encoded by this gene is an integral membrane protein and G protein-coupled receptor for prokineticins. The encoded protein is similar in sequence to GPR73， another G protein-coupled receptor for prokineticins. [provided by RefSeq， Jul 2008]。
