OBJECTIVE
This study aimed to identify novel isoforms of mouse succinate dehydrogenase complex flavoprotein subunit A (Sdha) arising from internal exon skipping, analogous to the process observed in human ortholog SDHA.
RESULTS
We identified a novel isoform, designated Δ3-10, which lacked the final 104 nucleotides of exon 3 and all of exons 4 through 10, yet did not alter the reading frame. The Δ3-10 Sdha cDNA was cloned into expression vectors, and overexpression resulted in a protein localized to the mitochondria. However, the endogenous Δ3-10 Sdha protein was not detected with the available antibodies.
目的
本研究旨在鉴定小鼠琥珀酸脱氢酶复合物黄素蛋白亚基A（Sdha）因内部外显子跳跃而产生的新型异构体，类似于在人类直系同源物SDHA中观察到的过程。
结果
我们鉴定出一种新型异构体，命名为Δ3-10，它缺少外显子3的最后104个核苷酸以及外显子4至10的所有外显子，但未改变阅读框。将Δ3-10 Sdha cDNA克隆到表达载体中，过表达产生了一种定位于线粒体的蛋白质。然而，用现有的抗体未检测到内源性Δ3-10 Sdha蛋白。
