ALK4

ALK4 (ACVR1B) is a versatile receptor that has a critical role in development. In Xenopus, ALK4 activates both sides of the developmental pathway: the TGFβ-driven left side with the ligands Xnrl and derriere and the BMP-driven right side with the ligand Vgl. This activation modulates mesoderm induction and dorsoanterior/ventroposterior development during primary axis formation. In mouse models, global knockout of Alk4 is embryonic lethal due to developmental impairment of the epiblast and extraembryonic ectoderm, leading to improper gastrulation. Activation of ALK4 can occur through a multitude of ligands, such as Activins, GDFs, and Nodal. Conditional knockouts of Alk4 in various adult tissues have been generated to analyze the impact of Alk4 systemically. Activin A signaling, mediated via ALK4, has a substantial role in reproduction. Trophoblast invasion is regulated through a canonical ALK4-mediated pathway, where upregulated SNAIL induces MMP-2 expression; knockdown of ALK4 attenuated this effect.
