HECTD3 is a gene that encodes a protein involved in the regulation of various cellular processes, including cell growth and division. It belongs to the HECT family of E3 ubiquitin ligases, which play a crucial role in tagging proteins for degradation. This process is essential for maintaining cellular homeostasis and responding to stress. Research has shown that HECTD3 may be linked to certain diseases, including some types of cancer. Its function in the ubiquitin-proteasome system highlights its importance in cellular signaling pathways. Understanding HECTD3 could provide insights into potential therapeutic targets for related health conditions.
