Genes affected

NPNT (HGNC:27405): (nephronectin) Predicted to enable integrin binding activity. Predicted to be involved in several processes, including cell-cell adhesion mediated by integrin; positive regulation of ERK1 and ERK2 cascade; and positive regulation of osteoblast differentiation. Predicted to act upstream of or within positive regulation of transforming growth factor beta receptor signaling pathway. Located in extracellular exosome. Part of collagen-containing extracellular matrix. [provided by Alliance of Genome Resources, Apr 2022]
