HECTD1 regulates the expression of SNAIL: Implications for epithelial‑mesenchymal transition.

ABSTRACT: As a transcription factor, SNAIL plays a crucial role in embryonic development and cancer progression by mediating epithelial‑mesenchymal transition (EMT); however, post‑translational modifications, such as ubiquitination, which control the degradation of SNAIL have been observed to affect its functional role in EMT. In a previous study by the authors, it was demonstrated that the HECT domain E3 ubiquitin ligase 1 (HECTD1) regulated the dynamic nature of adhesive structures. In the present study, HECTD1 was observed to interact with SNAIL and regulate its stability through ubiquitination, and the knockdown of HECTD1 increased the expression levels of SNAIL. HECTD1 was discovered to contain putative nuclear localization and export signals that facilitated its translocation between the cytop
