== Function ==
[https://www.uniprot.org/uniprot/CIF_PHOLL CIF_PHOLL] 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:19225106, PubMed:20870031). 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) (By similarity). 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 (By similarity). Also able to catalyze deamidation of 'Gln-40' of host ubiquitin in vitro; however, NEDD8 constitutes the preferred substrate in vivo (By similarity).[UniProtKB:Q63KH5]<ref>PMID:19225106</ref> <ref>PMID:19308257</ref> <ref>PMID:20870031</ref>
