Ubiquitin-like protein 5.

NEDD8; Ubiquitin-like protein which plays an important role in cell cycle control and embryogenesis. Covalent attachment to its substrates requires prior activation by the E1 complex uba-3-ula-1 and linkage to the E2 enzyme ubc-12. Attachment of ned-8 to cullins activates their associated E3 ubiquitin ligase activity, and thus promotes polyubiquitination and proteasomal degradation of cyclins and other regulatory proteins.

Stress activated transcription factor atfs-1; Acts as a transcription factor during mitochondrial stress by activating the mitochondrial unfolded protein response (mtUPR). Induces nuclear and mitochondrial gene transcription, including genes coding for mitochondrial chaperones and proteins involved in glycolysis, amino acid catabolism and innate immunity. Following mitochondrial stress, restores mitochondrial respiratory capacity by limiting the transcription of oxidative phosphorylation (OXPHOS) machinery genes and by promoting the assembly of OXPHOS complexes via the up-regulation of [...]

Ubiquitin-like protein atg-12; Ubiquitin-like protein involved in autophagy vesicles formation (By similarity). Conjugation with atg-5 through a ubiquitin- like conjugating system involving also atg-7 as an E1-like activating enzyme and atg-10 as an E2-like conjugating enzyme, is essential for its function (By similarity). Most likely a component of an atg-5-lgg- 3-atg-16 complex that promotes autophagosome formation by associating with lgg-2, but not lgg-1, at the preautophagosomal membrane. Probably, as part of an atg-5-lgg- 3-atg-16 complex, required for lgg-1 lipidation; the comple [...]

ATP-dependent Clp protease proteolytic subunit 1, mitochondrial; Clp cleaves peptides in various proteins in a process that requires ATP hydrolysis. Clp may be responsible for a fairly general and central housekeeping function rather than for the degradation of specific substrates; Belongs to the peptidase S14 family.

Small ubiquitin-related modifier; Ubiquitin-like protein which can be covalently attached to target lysines as a monomer. Does not seem to be involved in protein degradation and may function as an antagonist of ubiquitin in the degradation process. Plays a role in a number of cellular processes such as nuclear transport, DNA replication and repair, mitosis and signal transduction. Covalent attachment to its substrates requires prior activation by the E1 complex aos-1-uba-2 and linkage to the E2 enzyme ubc-9, and can be promoted by an E3 ligase such as gei-17. Required for embryonic dev [...]

Ubiquitin-fold modifier 1; Ubiquitin-like modifier which can be covalently attached via an isopeptide bond to substrate proteins as a monomer or a lysine- linked polymer (By similarity). The so-called ufmylation requires the ufm-1-activating E1 enzyme uba-5, the ufm-1-conjugating E2 enzyme ufc- 1, and probably the ufm-1-ligase E3 enzyme ufl-1. Belongs to the UFM1 family.

Autophagy-related protein 3.

Autophagy-related protein 5; Involved in autophagic vesicle formation (By similarity). Conjugation with lgg-3/ATG12, through a ubiquitin-like conjugating system involving atg-7 as an E1-like activating enzyme and atg-10 as an E2-like conjugating enzyme, is essential for its function (By similarity). Most likely a component of an atg-5-lgg-3-atg-16 complex that promotes autophagosome formation by associating with lgg-2, but not lgg-1, at the preautophagosomal membrane. Probably, as part of an atg-5-lgg-3-atg-16 complex, required for lgg-1 lipidation; the complex acts as an E3-like enzym [...]
