[[http://www.uniprot.org/uniprot/UBI4P_YEAST UBI4P_YEAST]] Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-6-linked may be involved in DNA repair; Lys-11-linked is involved in ERAD (endoplasmic reticulum-associated degradation) and in cell-cycle regulation; Lys-29-linked is involved in lysosomal degradation; Lys-33-linked is involved in kinase modification; Lys-48-linked is involved in protein degradation via the proteasome; Lys-63-linked is involved in endocytosis, and DNA-damage responses. Linear polymer chains formed via attachment by the initiator Met lead to cell signaling. Ubiquitin is usually conjugated to Lys residues of target proteins, however, in rare cases, conjugation to Cys or Ser residues has been observed. When polyubiquitin is free (unanchored-polyubiquitin), it also has distinct roles, such as in activation of protein kinases, and in signaling (By similarity).

[https://www.uniprot.org/uniprot/CIF_BURPS CIF_BURPS] Protein-glutamine deamidase effector that inhibits the host cell cycle and other key cellular processes such as the actin network and programmed-cell death (PubMed:19308257, PubMed:20688984, PubMed:19225106). Acts by mediating the side chain deamidation of 'Gln-40' of host NEDD8, converting it to glutamate, thereby abolishing the activity of cullin-RING-based E3 ubiquitin-protein ligase complexes (CRL complexes) (PubMed:20688984, PubMed:21903097). Inactivation of CRL complexes prevents ubiquitination and subsequent degradation of the cyclin-dependent kinase inhibitors CDKN1A/p21 and CDKN1B/p27, leading to G1 and G2 cell cycle arrests in host cells (PubMed:19308257). Deamidation of 'Gln-40' of host NEDD8 also triggers macrophage-specific programmed cell death (PubMed:23175788). Also able to catalyze deamidation of 'Gln-40' of host ubiquitin in vitro; however, NEDD8 constitutes the preferred substrate in vivo (PubMed:20688984). Also regulates the host NF-kappa-B signaling via activation of MAPK/ERK cascade: activation of host MAPK/ERK cascade is independent of CRL complexes inhibition, suggesting that Cif has other host protein targets than NEDD8 (PubMed:28166272, PubMed:29848489).<ref>PMID:19225106</ref> <ref>PMID:19308257</ref> <ref>PMID:20688984</ref> <ref>PMID:21903097</ref> <ref>PMID:23175788</ref> <ref>PMID:28166272</ref> <ref>PMID:29848489</ref>
