p70核糖体S6激酶(p70 S6 K)可以整合营养和生长因子信号,促进细胞生长和存活。对内蒙古绒山羊(Caprahircus)p70 S6 K基因40 S核糖体S6激酶1(S6 K1)(GenBank登录号GU 144017)及其3′端非编码区的cDNA进行了分子生物学鉴定。山羊S6 K1 cDNA全长2,272 bp,包括一个长1,578 bp的开放阅读框(ORF)和一段694个残基的3′端非编码序列,该序列由525个氨基酸组成,在第2218 ~ 2223位核苷酸处有一个多聚腺苷酸化信号。实时荧光定量PCR检测6种组织中S6 K1 mRNA的相对丰度,免疫组化检测心脏和睾丸中p70 S6 K的表达。在胎儿成纤维细胞中,p70 S6 K的磷酸化受到丝裂原活化蛋白激酶(MAPK)信号的调节。
p70 ribosomal S6 kinase (p70S6K) can integrate nutrient and growth factor signals to promote cell growth and survival. We report our molecular characterization of the complementary DNA (cDNA) that encodes the goat p70S6K gene 40S ribosomal S6 kinase 1 (S6K1) (GenBank accession GU144017) and its 3′ noncoding sequence in Inner Mongolia Cashmere goats (Capra hircus). Goat S6K1 cDNA was 2,272 bp and include an open reading frame (ORF) of 1,578 bp, corresponding to a polypeptide of 525 amino acids, and a 694-residue 3′ noncoding sequence with a polyadenylation signal at nucleotides 2,218 to 2,223. The relative abundance of S6K1 mRNA was measured by real-time PCR in 6 tissues, and p70S6K expression was examined by immunohistochemistry in heart and testis. The phosphorylation of p70S6K is regulated by mitogen-activated protein kinase (MAPK) signaling in fetal fibroblasts.
