AXIN is present in low concentrations in the cell and is considered to be the limiting component of the beta-catenin destruction complex in Xenopus; this may not be the case in mammalian cells, however (Lee et al, 2003; Tan et al, 2012). Cellular levels of AXIN are regulated in part through ubiquitin-mediated turnover. E3 ligases SMURF2 and RNF146 have both been shown to play a role in promoting the degradation of AXIN by the 26S proteasome (Kim and Jho, 2010; Callow et al, 2011; Zhang et al, 2011).
