B PF00240 ubiquitin Ubiquitin family Domain This family contains a number of ubiquitin-like proteins: SUMO (smt3 homologue) (see Swiss:Q02724), Nedd8 (see Swiss:P29595), Elongin B (see Swiss:Q15370), Rub1 (see Swiss:Q9SHE7), and Parkin (see Swiss:O60260). A number of them are thought to carry a distinctive five-residue motif termed the proteasome-interacting motif (PIM), which may have a biologically significant role in protein delivery to proteasomes and recruitment of proteasomes to transcription sites [5]. PFAM PF00240
A PF14755 ER-remodelling Intracellular membrane remodeller Domain This domain represents subunit nsp3 of the RNA-arteriviruses, such as porcine arterivirus PRRSV and equine arterivirus EAV, and is a tetraspanning transmembrane protein that contains a cluster of four highly conserved cysteine residues. These are predicted to reside in the first luminal domain of the protein. Arterivirus nsp3 proteins are uniformly predicted to contain four transmembrane helices, with the N and C termini of the protein residing in the cytoplasm. NSP3 are localised to the ER and appear to be essential for formation of double-membrane vesicles that originate from the ER during the life-cycle of the virus. PFAM PF14755
