Target Details

Target: IL-2 R beta & IL-2 R gamma

Background: Wilms' tumor 1 (WT1) is a transcription factor which plays a major role in cell proliferation, differentiation, survival, and apoptosis. WT1 was first identified as a tumor suppressor gene in Wilms' tumor. The expression of survival signaling genes, IL-2, IL-2RB, and IL-2RG, was also suppressed after WT1-siRNA treatment. In addition, the WT1 silencing also inhibited the S phase of the cell cycle and induced cell death.Moreover, transcriptional modulation of IL-2, IL-2RB, and IL2-2RG expression by WT1 was likely involved in this phenotypic change.

Molecular Weight: 51.3 kDa (IL-2 R beta)&54.6 kDa (IL-2 R gamma). Due to glycosylation, the protein migrates to 65-70 kDa&80-100 kDa based on Tris-Bis PAGE result.
