摘    要:根据哺乳动物脂肪酸结合蛋白基因序列设计一对引物对鸡基因组进行PCR扩增,将163bp扩增片段进行克隆和测序,并与猪的脂肪酸结合蛋白(fatty acid binding protein,FABP)基因序列进行同源性比较。该基因因片段与猪的心脏脂肪酸结合蛋白(heart fatty acid binding protein,H-FABP)基因有68%的同源性,与猪的脂肪型脂肪酸结合蛋白(adipocyte fatty acid binding protein,A-FABP)基因有75%的同源性,演绎成氨基酸之后与猪的脂肪型脂肪酸结合蛋白相应的氨基酸有75%的同源性。Northern结果表明该基因只在脂肪组织中表达。

关 键 词:  脂肪酸结合蛋白基因  单链构象多态性  克隆  测序

Cloning and Sequencing of Fatty Acid Binding Proteins Gene in Chicken
Abstract:A pair of primers was designed according to the sequence of mammal fatty acid binding protein (FABP) gene, then PCR amplified to chicken genome. After the product of PCR was cloned and sequenced, homologous comparison was done among porcine heart fatty acid binding protein gene and porcine adipocyte fatty acid binding protein gene. The result showed that the sequence of chicken FABP gene had 68% and 75% homology with porcine H FABP and A FABP gene respectively, and had 75% homology with porcine AFABP on amino acid level. The result of Northern showed that the gene only expressed in fat tissues.
Keywords:chicken  FABP  gene  SSCP
