SKI is a nuclear protein that forms homodimers and heterodimers and binds to DNA to function as transcriptional activators and repressors. The SKI oncoprotein dramatically affects cell growth, differentiation, and/or survival. SKI was shown to act in distinct signaling pathways including those involving nuclear receptors, transforming growth factor beta, and tumor suppressors. SKI inhibits transforming growth factor-beta (TGF-beta) signaling through interaction with Smad proteins. SKI represses Smad-mediated transcriptional activation, probably through its action as a transcriptional co-repressor. SKI also inhibits TGF-beta-induced downregulation of genes such as c-myc.
Suitable for use in Immunocytochemistry, Immunoprecipitation, and Western Blot. Other applications not tested.
Western Blot: 1-5ug/ml
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
