What pLDDT means and how to read it

Function

E3 protein ligase that mediates ufmylation, the covalent attachment of the ubiquitin-like modifier UFM1 to lysine residues on target proteins, and which plays a key role in various processes, such as ribosome recycling, response to DNA damage, interferon response or reticulophagy (also called ER-phagy) (PubMed:20018847, PubMed:20164180, PubMed:20228063, PubMed:25219498, PubMed:27351204, PubMed:30626644, PubMed:30783677, PubMed:32160526, PubMed:32807901, PubMed:35394863, PubMed:36121123, PubMed:36543799, PubMed:36893266, PubMed:37036982, PubMed:37311461, PubMed:37595036, PubMed:37795761, PubMed:38377992, PubMed:38383785, PubMed:38383789). Catalyzes ufmylation of many protein, such as…

Subunit structure

Catalytic component of the UFM1 ribosome E3 ligase (UREL) complex, composed of UFL1, DDRGK1 and CDK5RAP3 (PubMed:20018847, PubMed:20164180, PubMed:20228063, PubMed:25219498, PubMed:32160526, PubMed:36121123, PubMed:36543799, PubMed:37595036, PubMed:38383785, PubMed:38383789). Interacts with E2-like enzyme UFC1 (PubMed:20018847, PubMed:30886146, PubMed:37988244, PubMed:38383789). Interacts with…
