== Function ==
[https://www.uniprot.org/uniprot/ZY11B_HUMAN ZY11B_HUMAN] Serves as substrate adapter subunit in the E3 ubiquitin ligase complex ZYG11B-CUL2-Elongin BC. Acts to target substrates bearing N-terminal degrons for proteasomal degradation with the first four residues of substrates being the key recognition elements (PubMed:33093214, PubMed:34214466, PubMed:35636250). Prefers Nt-Gly but also has the capacity to recognize Nt-Ser, -Ala and -Cys (PubMed:36496439). Involved in the clearance of proteolytic fragments generated by caspase cleavage during apoptosis since N-terminal glycine degrons are strongly enriched at caspase cleavage sites. Also important in the quality control of protein N-myristoylation in which N-terminal glycine degrons are conditionally exposed after a failure of N-myristoylation (PubMed:31273098). In addition, plays a role in the amplification of cGAS to enhance innate immune response. Mechanistically, strengthens the processes of cGAS binding with dsDNA and assembling oligomers and also accelerates and stabilizes cGAS-DNA condensation, thereby enhancing production of antiviral IFNs and inflammatory cytokines (PubMed:36933219).<ref>PMID:31273098</ref> <ref>PMID:33093214</ref> <ref>PMID:34214466</ref> <ref>PMID:35636250</ref> <ref>PMID:36496439</ref> <ref>PMID:36933219</ref>
