The right distribution and activity of secreted signaling proteins called morphogens is necessary for most developmental processes. 2005; Ramirez-Weber and Kornberg, 1999; Roy et al., 2011). Nodal proteins, which participate in the TGF- category of signaling proteins, enjoy critical assignments in vertebrate advancement (Arnold and Robertson, 2009; Wakefield and Hill, 2013). They serve as mesendoderm… Continue reading The right distribution and activity of secreted signaling proteins called morphogens
