SMR3B Protein is an important oncogenic driver that promotes cancer progression and metastasis. SMR3B overexpression in multiple cancers has pleiotropic effects, causing cells to acquire hallmark traits such as sustained proliferative signaling, replicative immortality, genome instability and mutation, resistance to cell death, angiogenesis etc. In addition, up-regulation of SMR3B activates the Src kinase, which initiates a number of signal pathways culminating in the phosphorylation of ERK1/2, STAT3, and p130. SMR3B Protein, Human (HEK293, Fc) is the recombinant human-derived SMR3B protein, expressed by HEK293 , with C-mFc labeled tag.
