在这项研究中,我们研究了脂质激酶pi4p5 -激酶Iγ的剪接变化。我们在啮齿动物中发现了一种新的剪接变体。►我们发现这种新的变异具有广泛的组织分布。我们发现,通过鉴定一个新的人类剪接位点,人类也表达这种变体。►最后,我们证明了另一种已知的剪接变体,迄今为止被认为只存在于啮齿动物中,也存在于人类中。磷脂酰肌醇4-磷酸5-激酶Iγ (PIP5KIγ)受到广泛的c端剪接变异的影响,在人类中有四种变体,PIP5KIγ_v1, 2, 4和5,Schill和Anderson(2009)。首先,我们报道了一种新的啮齿动物剪接变体,其中包括以前啮齿类动物神经元特异性PIP5KIγ93独有的外显子Giudici等人(2006),但它忽略了PIP5KIγ93的c端外显子;该新变异在小鼠中表现出广泛的组织表达模式。其次,我们发现在人类中,从外显子16c开始有一个78个核苷酸的剪接位点,使得人类在大脑中特异性地表达PIP5KIγ93(我们现在称之为PIP5KIγ_v3),并且再次更广泛地表达这里描述的新变体,我们现在将其命名为PIP5KIγ_v6。
► In this study we investigate splice variation in the lipid kinase PI4P 5-kinase Iγ. ► We report a new splice variant in rodents. ► We show that this new variant has a wide tissue distribution. ► We show, by identifying a new human splice site, that humans also express this variant. ► Finally, we show that another known splice variant, hitherto thought to be present only in rodents, is also found in humans. Phosphatidylinositol 4-phosphate 5-kinase Iγ (PIP5KIγ) is subject to extensive C-terminal splice variation, with four variants, PIP5KIγ_v1, 2, 4 and 5, described in humans Schill and Anderson (2009). Here firstly, we report a new rodent splice variant, which includes the exon that was previously unique to the rodent neuron-specific PIP5KIγ93 Giudici et al. (2006), but which omits the C-terminal exon of PIP5KIγ93; this new variant shows a wide tissue expression pattern in mouse. Secondly, we show that in humans there is an alternative splicing site 78 nucleotides from the start of exon 16c, such that humans additionally express both PIP5KIγ93 (which we now call PIP5KIγ_v3) specifically in brain and, again expressed more widely, the new variant described here, which we now name PIP5KIγ_v6.
