| 摘 要： | 从小鼠cDNA序列入手,依据同源分析的电子克隆方法得到一个包含N末端乙酰转移酶结构域的人类新基因hNATL(Human NAT Like)。hNATL的cDNA长1803bp,编码区621bp,Genbank 登陆号AY632082。hNATL编码的蛋白长206个氨基酸残基,包含有N乙酰转移酶结构域。hNATL 基因定位于人染色体17q25．2区,包括6个外显子和5个内含子。基因表达汇编分析结果显示, hNATL在人脑和生殖腺中高表达。Northern杂交显示,在成年小鼠中hNATL在心脏,脾脏和卵巢中出现表达。整体原位杂交的结果显示,hNATL特异表达于E7．5和E8．5的小鼠胚胎脑部和HH10期鸡胚胎的头部。上述结果提示,hNATL对胚胎期脑的发育和成体中重要器官行使正常功能发挥十分重要的作用。

| Abstract: | A novel human gene hNATL (Human NAT Like) was cloned by in silico cloning and RT-PCR. hNATL cDNA is 1803bp in length with a 621bp coding region, and the Genbank accession No. is AY632082. hNATL encodes a protein of 206 amino acid residues which containing a N-acetyltransferase domain. hNATL is located on human chromosome 17q25.2 with 6 exons. Serial analysis of gene expression revealed that hNATL was highly expressed in human brain and gonad, while hNATL was expressed in heart, spleen and gonad of adult mouse. Whole-mount in situ hybridization showed that hNATL specifically expresses in E7.5 and E8.5 mouse embryo brains and in HH10 stage chicken embryo brain. These results suggest that hNATL may play an important role in the development of embryo brain and may also be important for function of adult brain and gonad. |
