Recently, HSP90AA1 has been shown to be a novel target for cancer therapy because its inhibition can enhance the degradation of its client proteins, typically receptor tyrosine kinases, signaling molecules and kinases, and transcription factors, to result in modulating many crucial cell functions, including survival, proliferation, metastasis, angiogenesis, cell cycle regulation, and apoptosis [27]. The gene discussed is NTRK1; the disease is cancer.
