Description

WTX (Wilms Tumor on the X; also FAM123B and AMER1) is a 190-200 kDa member of the FAM123 family of proteins. It is widely expressed in both adult and embryo and appears to have at least three functions: one, it binds WT1 in the nucleus and regulates cell differentiation; two, it associates with the plasma membrane and draws APC away from microtubules, thereby participating in intercellular junction integrity; and three, it binds beta -catenin and impacts WNT signaling. Human WTX is 1135 amino acids in length. It contains a PtdIns-P2 binding site (aa 2-209), an acidic domain (aa 370-411), and a Pro-rich region (aa 952-1104). There are three APC binding motifs (aa 280-368; 380-431; 717-834) and the beta -catenin binding region lies C-terminal to Gly368. There are two isoform variants. One is 150 kDa in size, nuclear in location, and shows a deletion of aa 50-326. A second shows a 19 aa substitution for aa 786-1135. Over aa 421-573, human WTX shares 89% aa identity with mouse WTX.
