39 results about "YAP1" patented technology

YAP1 (yes-associated protein 1), also known as YAP or YAP65, is a protein that acts as a transcriptional regulator by activating the transcription of genes involved in cell proliferation and suppressing apoptotic genes. YAP1 is inhibited in the Hippo signaling pathway which allows the cellular control of organ size and tumor suppression. YAP1 was first identified by virtue of its ability to associate with the SH3 domain of Yes and Src protein tyrosine kinases. YAP1 is a potent oncogene, which is amplified in various human cancers.

Yap1 inhibitors that target the interaction of yap1 with oct4

Binding of the transcriptional co-activator, YAP1, to the transcription factor Oct4, induces Sox2, which is a transcription actor necessary for the self-renewal of stem-like cells from non-small celllung cancer. The WW domain of YAP1 binds to the PPxY motif of Oct4 to induce Sox2. Delivering a peptide corresponding to the WW domain could prevent the induction of Sox2 and stemness. Similarly, peptides and mimetics of the PPxY motif would be able to inhibit stemness. Disclosed are compounds that affect the Yap1:Oct4 interaction.
