Abstract

A bovine adrenal cDNA clone encoding the entire alpha subunit of the GTP-binding regulatory protein that stimulates adenylate cyclase (Gs) was isolated and sequenced. This cDNA directed the synthesis of the larger, 52-kDa form of the polypeptide in COS cells, even though the clone appeared to encode a 46-kDa protein. Comparison of the deduced amino acid sequence of Gs alpha with the alpha subunit of another G protein, transducin, revealed striking homologies.

摘要

分离并测序了一个牛肾上腺cDNA克隆,该克隆编码刺激腺苷酸环化酶(Gs)的GTP结合调节蛋白的整个α亚基。尽管该克隆似乎编码一种46 kDa的蛋白质,但此cDNA在COS细胞中指导合成了较大的、52 kDa形式的多肽。将Gsα推导的氨基酸序列与另一种G蛋白转导素的α亚基进行比较,发现了显著的同源性。
