A clone MA2C4 encoding the murine homologue of adrenoceptor alpha 2C4 was identified, amplified and purified from a mouse genomic library (EMBL-3). The Pstl-EcoRl digested fragment (2409 base pairs) of the clone contains the nucleotide sequence encoding a putative receptor protein (458 amino acids), which is highly homologous in the transmembrane and G protein-coupling domains to the human and rat isoceptors. The 5' untranslated region (0.4kb) is characterized by high GC content and CpG island count whereas a polyadenylation signal (AATAAA) is located 481 base pairs downstream from the termination codon in the 3' untranslated region (0.6kb).
从小鼠基因组文库(EMBL - 3)中鉴定、扩增并纯化出一个编码肾上腺素能α2C4受体小鼠同源物的克隆MA2C4。该克隆经Pstl - EcoRl酶切的片段(2409个碱基对)包含编码一种假定受体蛋白(458个氨基酸)的核苷酸序列,该序列在跨膜和G蛋白偶联结构域与人和大鼠的同种受体高度同源。5'非翻译区(0.4kb)的特征是GC含量高和CpG岛数量多,而一个聚腺苷酸化信号(AATAAA)位于3'非翻译区(0.6kb)终止密码子下游481个碱基对处。
