 398-473 7.97e-22

Replication stress response SDE2 C-terminal; This domain represents the C-terminal region of the Replication stress response SDE2, a genome surveillance factor. It contains the DNA-binding SAP domain, frequently found in proteins involved in DNA repair. SDE2 C-terminal domain must be cleaved from its N-terminal at a diglycine motif within the ubiquitin-like fold, after Proliferating cell nuclear antigen (PCNA) interaction. This generates a functional protein that negatively regulates damage-inducible PCNA monoubiquitination, which then is proteolytically degraded to allow S phase progression and replication fork recovery in response to DNA damage.

 149-236 8.92e-14

first ubiquitin-like (Ubl) domain located at the N-terminus of coronavirus SARS-CoV non-structural protein 3 (Nsp3) and related proteins; This ubiquitin-like (Ubl) domain (Ubl1) is found at the N-terminus of coronavirus Nsp3, a large multi-functional multi-domain protein which is an essential component of the replication/transcription complex (RTC). The functions of Ubl1 in CoVs are related to single-stranded RNA (ssRNA) binding and to interacting with the nucleocapsid (N) protein. SARS-CoV Ubl1 has been shown to bind ssRNA having AUA patterns, and since the 5'-UTR of the SARS-CoV genome has a number of AUA repeats, it may bind there. In mouse hepatitis virus (MHV), this Ubl1 domain binds the cognate N protein. Adjacent to Ubl1 is a Glu-rich acidic region (also referred to as hypervariable region, HVR); Ubl1 together with HVR has been called Nsp3a. Currently, the function of HVR in CoVs is unknown. This model corresponds to one of two Ubl domains in Nsp3; the other is located N-terminal to the papain-like protease (PLpro) and is not represented by this model.

 149-236 8.92e-14

Silencing defective 2 N-terminal ubiquitin domain; Sde2 (silencing defective 2) is a ubiquitin-fold-containing splicing regulator that supports splicing of selected pre-mRNAs in an intron-specific manner in Schizosaccharomyces pombe. Both fission yeast and human Sde2 are translated as inactive precursor proteins harbouring the ubiquitin-fold domain linked through an invariant GGKGG motif to a C-terminal domain. The Sde2 protein has a ubiquitin-fold at its N-terminus, which must be cleaved by the ubiquitin-specific proteases (USPs) Ubp5 and Ubp15. After cleavage, the C-terminal domain of Sde2, which starts with a lysine, gets incorporated into the spliceosome. This entry represents the ubiquitin fold N-terminal domain found in Sde2 proteins.
