title: Essential role of Ufm1 conjugation in the hematopoietic system.
abstract: Protein modification by ubiquitin (Ub) and ubiquitin-like (Ubl) proteins plays a pivotal role in a wide range of cellular functions and signaling pathways. The Ufm1 conjugation system is a novel ubiquitin-like system that consists of Ufm1, Uba5 (E1), Ufc1 (E2), and less defined E3 ligase(s) and targets. Despite its discovery more than a decade ago, its biological functions and working mechanism remains poorly understood. Recent genetic studies using knockout mouse models provide unambiguous evidence for the indispensable role of the Ufm1 system in animal development and hematopoiesis, especially erythroid development. In this short review, we summarize the recent progress on this important protein modification system and highlight potential challenges ahead. Further elucidation of the function and working mechanism of the ufmylation pathway would provide insight into disease pathogenesis and novel therapeutic targets for blood-related diseases such as anemia.
