Netrin mediated repulsion signals
Unc5 netrin receptors mediate repellent responses to netrin. Four Unc5 members have been found in humans: Unc5A, B, C and D. Different studies have suggested that long-range repulsion to netrin requires the cooperation of Unc5 and DCC, but that Unc5 without DCC is sufficient for short-range repulsion. The binding of netrin to Unc5 triggers the phosphorylation of Unc5 in its ZU-5 domain. Several proteins have been proposed to interact with Unc5 family members in mediating a repellent response, including tyrosine phosphatase Shp2, the F-actin anti-capping protein Mena, and ankyrin.
Neurogenesis is the process by which neural stem cells give rise to neurons, and occurs both during embryonic and perinatal development as well as in specific brain lineages during adult life (reviewed in Gotz and Huttner, 2005; Yao et al, 2016; Kriegstein and Alvarez-Buylla, 2009).
As early steps towards capturing the array of processes by which a fertilized egg gives rise to the diverse tissues of the body, examples of several processes have been annotated. Aspects of processes involved in most developmental processes, transcriptional regulation of pluripotent stem cells, gastrulation, and activation of HOX genes during differentiation are annotated. More specialized processes include nervous system development , aspects of the roles of cell adhesion molecules in axonal guidance and myogenesis, transcriptional regulation in pancreatic beta cell, cardiogenesis, transcriptional regulation of granulopoeisis, transcriptional regulation of testis differentiation, transcriptional regulation of white adipocyte differentiation, and molecular events of "nodal" signaling, LGI-ADAM interactions, and keratinization.
