This gene encodes a downstream nuclear effector of the Hippo signaling pathway which is involved in development, growth, repair, and homeostasis. This gene is known to play a role in the development and progression of multiple cancers as a transcriptional regulator of this signaling pathway and may function as a potential target for cancer treatment. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Aug 2013] CIViC Summary for YAP1 Gene
Forensic Context
A study in human corpus cavernosum tissue demonstrated that the YAP1 protein, a Hippo signalling pathway effector, was detected in vascular smooth muscle cells, cavernosal trabecular smooth muscle cells, and myofibroblasts, with nuclear-localized protein increased in erectile dysfunction patients' endothelial and smooth muscle cells [Zhao et al. DOI:10.1038/s41467-022-31950-9]. In human and mouse keratinocytes, the YAP1 transcription factor was validated as a direct target of miR-483-3p, where its down-regulation contributed to the antiproliferative effect controlling keratinocyte growth arrest during wound healing [Bertero et al. DOI:10.1096/fj.10-168401]. A study in mice demonstrated that the YAP1 is a core component of the Hippo signaling pathway whose transcriptional co-activator activity is inhibited when this pathway is activated [Li et al. DOI:10.1038/s41598-025-94820-6].
