Product Overview
This rabbit polyclonal antibody targets smad nuclear-interacting protein 1 (gene SNIP1) in human samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 45.8 kDa, and the supplier reports an observed band at about 46 kDa.
SNIP1 is a nuclear protein that is part of the spliceosome and is involved in microRNA biogenesis. It can dampen NF-κB and TGF-β signaling by competing for the coactivators CBP/p300, and it may influence cyclin D1 mRNA stability.

Immunogen
Recombinant human SNIP1 fragment (His16–Glu372), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places smad nuclear-interacting protein 1 in the nucleus. Tissue expression noted by UniProt (human): Ubiquitous, with highest expression in heart and skeletal muscle. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
