Genes affected

KLB (HGNC:15527): (klotho beta) Enables fibroblast growth factor binding activity and fibroblast growth factor receptor binding activity. Predicted to be involved in fibroblast growth factor receptor signaling pathway. Predicted to act upstream of or within positive regulation of MAPKKK cascade by fibroblast growth factor receptor signaling pathway and positive regulation of cell population proliferation. Predicted to be located in plasma membrane. Predicted to be active in endoplasmic reticulum. [provided by Alliance of Genome Resources, Apr 2022]
