我们以前曾报道过动力蛋白轻链km 23 -1和km 23 -2是哺乳动物细胞中TGFβ信号传导所必需的。在这里,我们描述了斑马鱼动力蛋白轻链的km 23/DYNLRB/LC 7/robl家族的另一个成员,称为zkm 23,其也参与TGFβ信号传导。在TGFβ刺激后,zkm 23迅速磷酸化。TGFβ RII激酶活性是zkm 23磷酸化所必需的,而组成型活性TGFβ RI不诱导磷酸化。此外,TGFβ刺激zkm 23动力蛋白轻链快速募集到动力蛋白复合物的动力蛋白中间链,并且这种相互作用需要TGFβ RII激酶。最后,使用吗啉代寡核苷酸阻断zkm 23导致TGFβ介导的转录反应的抑制。因此,我们的研究结果首次证明了在培养的斑马鱼卵泡细胞中,动力蛋白轻链zkm 23是TGFβ信号传导所必需的。
We have previously reported that the dynein light chains km23-1 and km23-2 are required for TGFβ signaling in mammalian cells. Here we describe another member of the km23/DYNLRB/LC7/robl family of dynein light chains in zebrafish, termed zkm23, which is also involved in TGFβ signaling. zkm23 was rapidly phosphorylated after TGFβ stimulation. TGFβ RII kinase activity was absolutely required for zkm23 phosphorylation, whereas a constitutively active TGFβ RI did not induce phosphorylation. Further, TGFβ stimulated a rapid recruitment of the zkm23 dynein light chain to the dynein intermediate chain of the dynein complex, and the TGFβ RII kinase was required for this interaction. Finally, blockade of zkm23 using morpholino oligos resulted in an inhibition of TGFβ-mediated transcriptional responses. Thus, our results demonstrate for the first time that the dynein light chain zkm23 is required for TGFβ signaling in cultured zebrafish ovarian follicle cells.
