We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Ufmylation is a type of post-translational modification that deals with fine-tuned and complex cellular activities and is involved in reticulophagy induced by ER stress<ref>PMID:31129212</ref>. Ufmylation is aribosomal modification specialized to facilitate metazoan-specific protein biogenesis at the ER<ref>PMID:30626644</ref>. |
