WW domain-containing transcription regulator protein 1 (WWTR1), also known as Transcriptional coactivator with PDZ-binding motif (TAZ), is a protein that in humans is encoded by the WWTR1 gene. WWTR1 acts as a transcriptional coregulator and has no effect on transcription alone. When in complex with transcription factor binding partners, WWTR1 helps promote gene expression in pathways associated with development, cell growth and survival, and inhibiting apoptosis. Aberrant WWTR1 function has been implicated for its role in driving cancers. WWTR1 is often referred to as TAZ due to its initial characterization with the name TAZ. However, WWTR1 (TAZ) is not to be confused with the protein tafazzin, which originally held the official gene symbol TAZ, and is now TAFAZZIN.

Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (HA723764) at 1/5,000 dilution was used in primary antibody dilution (K1803) at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1/50,000 dilution was used for 1 hour at room temperature.
TAZ / WWTR1 was immunoprecipitated from 0.2 mg PANC-1 cell lysate with HA723764 at 2 µg/10 µl beads. Western blot was performed from the immunoprecipitate using HA723764 at 1/5,000 dilution. HRP Conjugated Anti-Rabbit IgG for IP Nano-secondary antibody at 1/5,000 dilution was used for 1 hour at room temperature.
