Rabbit anti-CSN2 IHC Antibody Affinity Purified

CSN2 is one of eight subunits (CSN1 to 8) of the highly conserved COP9 signalsome (CSN) complex originally identified as a regulator of light-mediated development in Arabidopsis. Characterization of CSN from yeast to mammals reveals a function as a modulator of signal transduction pathways involved in a variety of cellular and developmental processes. One of the major functions of the CSN is the regulation of protein degradation via intersection with the ubiquitin-proteasome pathway and regulation of E3-ubiquitin ligases. CSN2 has also been demonstrated to interact with the sin3A corepressor complex as well as the thyroid hormone and vitamin D3 receptor to mediate gene repression.
