Ubiquitin-fold modifier 1 (UFM1)

Ubiquitin-like modifier that may be covalently attached through an isopeptide bond to substrate proteins as a monomer or a lysine-linked polymer (PubMed:15071506, PubMed:20018847). The so- called ufmylation, requires the UFM1-activating E1 enzyme UBA5, the UFM1-conjugating E2 enzyme UFC1, as well as the UFM1-ligase E3 enzyme UFL1 (PubMed:15071506, PubMed:20018847).

This post-translational modification on lysine residues of proteins may play a crucial role in several of cellular processes (PubMed:15071506, PubMed:20018847). TRIP4 ufmylation may for example play a role in atomic receptors-mediated transcription (PubMed:25219498).
