Background

  • Function

    YAP1 (Yes-associated protein 1) is a transcriptional co-activator that functions as a major downstream effector of the Hippo signaling pathway, integrating mechanical and cellular signals to regulate cell proliferation, tissue homeostasis, organ size control, and transcriptional programs mediated by TEAD transcription factors[4]. When the Hippo kinase cascade is active, LATS1/2-mediated phosphorylation restricts YAP1 nuclear localization and suppresses expression of genes involved in proliferation, migration, and epithelial-mesenchymal transition (EMT) [4]. Mechanistically, YAP1 lacks intrinsic DNA-binding activity and exerts most of its transcriptional output through TEAD family proteins, which recruit YAP1 to enhancer elements and drive target gene activation[1]. Dysregulated YAP1 signaling has been associated with cancer initiation, tumor progression, metastasis, therapy resistance, and stem cell-related phenotypes, making the Hippo-YAP1-TEAD axis an important experimental model for studying oncogenic transcriptional regulation[2][5]. Compared with its closely related paralog TAZ (WWTR1), YAP1 exhibits distinct alternatively spliced isoforms, and characterization of these isoforms has provided insight into structural and functional diversity within Hippo pathway signaling[6]. For experimental applications, disruption of the YAP1-TEAD complex is widely used to investigate YAP-dependent transcription, and verteporfin has been reported to suppress YAP-TEAD activity and serves as a commonly employed pharmacological tool in preclinical studies[3][7].

  • Subcellular Localization

    Cytoplasm; Nucleus; Cell junction, tight junction; Cell membrane

  • Expression


    Tissue_specificity:Increased expression has been observed in certain liver and prostate cancers. A subtype (protein level) lacking the transcriptional activation domain has been found in striatal neurons of Huntington's disease.

    Induction:Induced in the hours following cyclic mechanical strain in keratinocytes

  • Subunit

    Part of a complex when phosphorylated that contains DSG3, PKP1, YAP1 and YWHAG; the complex is required for localization of DSG3 and YAP1 to the cell membrane in keratinocytes (PubMed:31835537). Binds to the SH3 domain of the YES kinase. Binds to WBP1 and WBP2 (PubMed:9202023). Binds, in vitro, through the WW1 domain, to neural isoforms of ENAH that contain the PPSY motif (By similarity). The phosphorylated form interacts with YWHAB (PubMed:17974916). Interacts (via WW domains) with LATS1 (via PPxY motif 2) (PubMed:18158288). Interacts with LATS2 (PubMed:18158288). Interacts with TEAD1, TEAD2, TEAD3 and TEAD4 (PubMed:18579750, PubMed:20123905, PubMed:20123908). Interacts with TP73 (PubMed:18280240). Interacts with RUNX1 (PubMed:18280240). Interacts with HCK (PubMed:17535448). Interacts (via WW domains) with PTPN14 (via PPxY motif 2); this interaction leads to the cytoplasmic sequestration of YAP1 and inhibits its transcriptional coactivator activity (PubMed:22525271). Interacts (when phosphorylated at Ser-127) with SMAD2, SMAD3 and WWTR1 (By similarity). Interacts with PRRG2 (via cytoplasmic domain) (PubMed:17502622). Interacts (via WW domains) with PRRG4 (via cytoplasmic domain) (PubMed:23873930). Interacts (phosphorylated) with CLDN18; the interaction sequesters YAP1 away from the nucleus and thereby restricts transcription of YAP1 target genes (By similarity). Interacts with SMAD1 (PubMed:21685363). Interacts with AMOTL2, the interaction is required for ubiquitination of AMOTL2 and localization of YAP1 to tight junctions (PubMed:21205866, PubMed:26598551). Interacts with AMOT isoform 1; the interaction facilitates translocation of YAP1 to the cytoplasm and tight junctions (PubMed:21205866)
