金华猪PYY基因的克隆与定位

摘要

肽YY(PYY)是胃肠道分泌的一种激素,具有抑制食欲的作用.本研究应用PCR技术扩增得到金华猪PYY基因序列为532 bp,并应用IMpRH辐射杂种板将其定位在猪15号染色体88.5～89.3 cM的位置.%The peptide YY (PYY) is released from endocrine L-cells of the distal digestive tract. It has been reported to inhibit food intake in animals. In this study, PYY gene was identified of 532 bp in Jinhua pigs by PCR and was located at 88.5～89.3 cM of 15 chromosome in swine by IMpRH panel.
