DESCRIPTION

Also known as TX1B3_HUMAN, TAX1BP3, TIP1. May regulate a number of protein-protein interactions by competing for PDZ domain binding sites. Binds CTNNB1 and may thereby act as an inhibitor of the Wnt signaling pathway. Competes with LIN7A for KCNJ4 binding, and thereby promotes KCNJ4 internalization. May play a role in the Rho signaling pathway. May play a role in activation of CDC42 by the viral protein HPV16 E6. Interacts (via its PDZ domain) with GLS2. Interacts (via its PDZ domain) with RTKN (via the C-terminal region); this interaction facilitates Rho-mediated activation of the FOS serum response element (SRE). Interacts (via its PDZ domain) with CTNNB1; this interaction inhibits the transcriptional activity of CTNNB1. Interacts with HTLV-1 TAX protein. Interacts (via PDZ domain) with ARHGEF16. Interacts (via PDZ domain) with KCNJ4 (via C-terminus). Competes with LIN7A for KCNJ4 binding. Interacts with ADGRB2 (PubMed:21787750).
