Based on limited published evidence, TRIM49C is an E3 ubiquitin protein ligase with protein binding capacity localized to the cytoplasm. GO annotations indicate roles in innate immune response and gene expression regulation. TRIM49C mutations have been identified as significantly mutated genes in gastric cancer across multiple ancestries 1, and recurrent TRIM49C mutations generate neoantigens with potential immunotherapeutic applications in gastric cancer patients 2. Specific molecular mechanisms and functional details remain largely unexplored.
