  • Znf45l, containing classical $C_2H_2$ domains, is a novel member of Zinc finger proteins in zebrafish. In vertebrates, TGF-${\beta}$ signaling plays a critical role in hematopoiesis. Here, we showed that Znf45l is expressed both maternally and zygotically throughout early development. Znf45l-depleted Zebrafish embryos display shorter tails and necrosis with reduced expression of hematopoietic maker genes. Furthermore, we revealed that znf45l locates downstream of TGF-${\beta}$ ligands and maintains normal level of TGF-${\beta}$ receptor type II phosphorylation. In brief, our results indicate that znf45l affects initial hematopoietic development through regulation of TGF-${\beta}$ signaling.
