HECTD1 is a gene that provides instructions for making a protein involved in cellular processes, particularly in the regulation of protein degradation. This protein is part of the HECT family of E3 ubiquitin ligases, which play a crucial role in tagging proteins for destruction, thereby maintaining cellular balance and function. Mutations or alterations in the HECTD1 gene have been linked to various health conditions, including certain developmental disorders. Research continues to explore its functions and implications in diseases, highlighting the importance of understanding this gene in the context of genetics and cell biology.
