YES1 (Yamaguchi sarcoma viral oncogene homolog 1) is a non-receptor tyrosine kinase belonging to the SRC family kinases (SFKs), which play crucial roles in regulating cell proliferation, differentiation, adhesion, and survival. Discovered as a homolog of the v-Yes oncogene from the Yamaguchi sarcoma virus, YES1 is evolutionarily conserved and shares structural homology with c-SRC, including SH3. SH2. and kinase domains. It is activated by autophosphorylation or upstream signals and participates in multiple signaling pathways, such as PI3K/AKT, MAPK/ERK, and STAT3. often interacting with growth factor receptors (e.g., EGFR, PDGFR).
Recombinant YES1 protein is engineered for in vitro studies to elucidate its biological functions and therapeutic potential. Produced via bacterial (e.g., E. coli) or mammalian expression systems, the recombinant protein retains enzymatic activity and structural integrity, enabling kinase assays, inhibitor screening, and interaction studies. Its applications span cancer research, as YES1 is implicated in tumor progression, metastasis, and drug resistance. Overexpression or hyperactivation of YES1 has been observed in lung, breast, and ovarian cancers, correlating with poor prognosis. Targeting YES1 with small-molecule inhibitors (e.g., dasatinib, bosutinib) is being explored, though challenges like off-target effects and resistance necessitate further research.
Structural studies using recombinant YES1 have revealed autoinhibitory conformations and regulatory mechanisms, aiding in the design of selective inhibitors. Additionally, it serves as a tool to study SFK redundancy and tissue-specific signaling. Despite advancements, the complexity of YES1's crosstalk with other kinases and pathways underscores the need for continued investigation. Recombinant YES1 thus remains a critical resource for dissecting oncogenic signaling and advancing targeted cancer therapies.
