The RNA-binding protein Seb4/RBM24 is a direct target of MyoD and is required for myogenesis during Xenopus early development

The RNA-binding protein Rbm24 is transiently expressed in myoblasts and is required for myogenic differentiation during vertebrate development

RNA-binding proteins (RBP) contribute to gene regulation through post-transcriptional events. Despite the important roles demonstrated for several RBP in regulating skeletal myogenesis in vitro, very few RBP coding genes have been characterized during skeletal myogenesis in vertebrate embryo. In the present study we report that Rbm24, which encodes the RNA-binding motif protein 24, is required ...

Seb4 – an RNA-binding protein as a novel regulator of myogenesis during early development in Xenopus laevis

Expression of hsp90 Alpha and hsp90 Beta during Xenopus laevis Embryonic Development

Background: Members of the eukaryotic Hsp90 family function as important molecular chaperones in the assembly, folding and activation of cellular signaling in development. Two hsp90 genes, hsp90 alpha and hsp90 beta, have been identified in fish and homeothermic vertebrates but not in poikilothermic vertebrates. In the present study, the expression of hsp90 alpha and hsp90 beta genes in Xenopus...

FHL3 binds MyoD and negatively regulates myotube formation.

MyoD initiates muscle differentiation and promotes skeletal myogenesis by regulating temporal gene expression. MyoD-interacting proteins induce regulatory effects, and the identification of new MyoD-binding partners may provide mechanistic insights into the regulation of gene expression during myogenesis. FHL3 is one of three members of the FHL protein family that are expressed in skeletal musc...

Integrin Linked Kinase (X-ILK) Function during Embryonic Development and within Adult Tissues of Xenopus laevis

Integrin linked kinase (ILK) is a serine/threonine protein kinase implicated in the phosphatidylinositol 3’kinase (PI3’K) pathway. Integrin linked kinase has been investigated in different organisms such as mammalian systems (human, mice, rat), insects (Drosophila) and nematodes (Cenorhabditis elegans), however to date little data regarding ILK research on amphibians has been reported. In...
