phosphocholine cytidylyltransferase is the rate-controlling enzyme in phosphatidylcholine biosynthesis and is essential for the survival of eukaryotic cells. The murine cDNA for the cytidylyltransferase was cloned and sequenced. A genomic clone was isolated and the chromosomal location of the Ctpct locus determined by Southern blot hybridization of DNAs from a panel of interspecific backcross progeny derived from matings of [(C57BL/6J x Mus spretus)F1 x C57BL/6J] mice. These data place the Ctpct gene on mouse chromosome 16 between the Smst and Stf-1 genes.
磷酸胆碱胞苷转移酶是磷脂酰胆碱生物合成中的限速酶,对真核细胞的存活至关重要。克隆并测序了胞苷转移酶的小鼠cDNA。分离出一个基因组克隆,并通过对一组源自[(C57BL/6J×小家鼠)F1×C57BL/6J]小鼠杂交后代的种间回交子代DNA进行Southern印迹杂交,确定了Ctpct基因座的染色体定位。这些数据将Ctpct基因定位于小鼠16号染色体上Smst和Stf-1基因之间。
