Ift172编码一种基因产物,该基因产物是介导鞭毛内运输(IFT)复合物的一部分,IFT是纤毛发生和维持所必需的过程。对小鼠的遗传研究提供了证据,表明Ift172也在hedgehog信号传导中发挥作用。Ift172在小鼠胚胎第11天的破坏与死亡有关,限制了研究了解Ift172在后期发育和成年中的作用。为了进一步了解Ift172的后期作用,我们产生了带有Ift172条件等位基因的小鼠。我们通过使用由prx1增强子引导的CRE表达来破坏发育肢体中的条件Ift172等位基因,证实了被破坏等位基因的表型。
Ift172 encodes a gene product that is part of a complex that mediates intraflagellar transport (IFT), a process necessary for the genesis and maintenance of cilia. Genetic studies in mice have offered evidence that Ift172 also plays a role in hedgehog signaling. Disruption of Ift172 in mice is associated with lethality at about embryonic day 11, limiting studies to understand the role for Ift172 in later development and the adult. To further our understanding of the later roles of Ift172, we have generated mice with a conditional allele for Ift172. We have confirmed the phenotype of the disrupted allele by using CRE expression directed by the prx1 enhancer to disrupt the conditional Ift172 allele in the developing limb.
