AMOT (130 KDa isoform) and AMOTL1 can each bind WWTR1 (TAZ) and sequester it in the cytosol. AMOTL2 - WWTR1 binding has not been studied but is inferred to occur from the presence of key binding sequence motifs in AMOTL2 protein and from its known binding activity with YAP1, a WWTR1 homolog. These interactions are not dependent on WWTR1 phosphorylation and may thus be a means of negatively regulating WWTR1 activity in addition to the ones dependent on Hippo pathway-dependent phosphorylation. AMOT - WWTR1 binding is dependent on sequence motifs in the amino terminal portions of the AMOT proteins (and that are absent from the AMOT 80 KDa isoform) (Chan et al. 2011).
