 166-282 9.27e-34

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.

 166-282 9.27e-34

Autophagy protein Atg8 ubiquitin like; Light chain 3 is proposed to function primarily as a subunit of microtubule associated proteins 1A and 1B and that its expression may regulate microtubule binding activity. Autophagy is generally known as a process involved in the degradation of bulk cytoplasmic components that are non-specifically sequestered into an autophagosome, where they are sequestered into double-membrane vesicles and delivered to the degradative organelle, the lysosome/vacuole, for breakdown and eventual recycling of the resulting macromolecules. The yeast proteins are involved in the autophagosome, and Atg8 binds Atg19, via its N-terminus and the C-terminus of Atg19.

ubiquitin-like (Ubl) domain found in autophagy-related 8 (ATG8) and similar proteins; The ATG8 family of proteins constitute a single member in Saccharomyces cerevisiae, Atg8p, and multiple homologs in higher eukaryotes, they are multifunctional ubiquitin-like (Ubl) key regulators of autophagy. The ATG8 system is a Ubl conjugation system that is essential for autophagosome formation. In the ATG8 system, a cysteine protease (ATG4) cleaves a C-terminal arginine from ATG8, and then the exposed C-terminal glycine is conjugated to phosphatidylethanolamine (PE) by ATG7, an E1-like enzyme, and ATG3, an E2-like enzyme. The mammalian ATG8 family is classified into three subfamilies: i) MAP1LC3 (microtubule associated protein 1 light chain 3) which includes MAP1LC3A, MAP1LC3B, MAP1LC3B2, and MAP1LC3C, ii) GABARAP (GABA type A receptor associated protein) which includes GABARAP, GABARAPL1, and GABARAPL3, and iii) GABARAPL2 (GABA type A receptor associated protein like 2), also known as GATE-16 (golgi-associated adenosine triphosphatase enhancer of 16 kDa).

These proteins are multifunctional ubiquitin-like (Ubl) key regulators of autophagy. ATG8 is characterized by a C-terminal ubiquitin-like (Ubl) domain with a short N-terminal extension. The covalent attachment of ATG8 to phosphatidylethanolamine (PtdEth) at the autophagosomal membrane places it at a crucial juncture during autophagosome formation. ATG Ubl proteins such as Saccharomyces cerevisiae Atg8p undergo a unique Ubl conjugation, a process essential for autophagosome formation.

 155-282 3.83e-25

ubiquitin-like (Ubl) domain found in gamma-aminobutyric acid receptor-associated protein (GABARAP); GABARAP (also termed GABA(A) receptor-associated protein, ATG8A, or MM46) has been implicated in intracellular protein trafficking. It is a cytosolic protein that is localized to transport vesicles, the Golgi network and the endoplasmic reticulum. It interacts with the intracellular domain of the gamma2 subunit of GABA(A) receptors, and thus functions as a trafficking modulator implicated in the intracellular trafficking of GABA(A) receptor. GABARAP also acts as a Ubl modifier belonging to the ATG8 (autophagy-related 8) protein family, which is essential for autophagosome biogenesis and maturation. GABARAP recruits phosphatidylinositol 4-kinase II alpha (PI4KIIalpha) as a specific downstream effector, and regulates phosphatidylinositol 4-phosphate (PI4P)-dependent autophagosome lysosome fusion.

ubiquitin-like (Ubl) domain found in gamma-aminobutyric acid receptor-associated protein (GABARAP) and similar proteins; sub-family of the autophagy-related 8 (ATG8) protein family; GABARAP (also termed GABA(A) receptor-associated protein, ATG8A, or MM46) has been implicated in intracellular protein trafficking. It is a cytosolic protein, localized to transport vesicles, the Golgi network and the endoplasmic reticulum. It interacts with the intracellular domain of the gamma2 subunit of GABA(A) receptors, and thus, functions as a trafficking modulator implicated in the intracellular trafficking of GABA(A) receptor. GABARAP also acts as a Ubl modifier belonging to the ATG8 (autophagy-related 8) protein family which is essential for autophagosome biogenesis and maturation. GABARAP recruits phosphatidylinositol 4-kinase II alpha (PI4KIIalpha) as a specific downstream effector, and regulates phosphatidylinositol 4-phosphate (PI4P)-dependent autophagosome lysosome fusion. This sub-family also includes GABARAPL1 (also termed GABA(A) receptor-associated protein-like, or GEC1), GABARAPL2/GATE-16, and GABARAPL3. GABARAPL1 has been involved in the intracellular transport of receptors via interactions with tubulin and GABA(A) or kappa opioid receptors. GABARAPL1 is also a Ubl modifier that functions as a mediator involved in androgen-regulated autophagy process. It is transcriptionally modulated by androgen receptor (AR) and has a repressive role in autophagy. In addition, GABARAPL1 is required for increased membrane expression of epidermal growth factor receptor (EGFR) during hypoxia, suggesting a possible role in the trafficking of these membrane proteins. GABARAPL1 may also play a key role in several important biological processes such as cancer or neurodegenerative diseases. Low expression of GABARAPL1 is associated with poor prognosis of patients with hepatocellular carcinoma.

 154-282 3.00e-22

ubiquitin-like (Ubl) domain found in microtubule associate protein 1 light chain 3A (MAP1LC3A); Autophagy is an essential intracellular process that targets large protein complexes, bacterial pathogens, and organelles for degradation. MAP1LC3A is belong to MAP1LC3 (short name LC3) family proteins. MAP1LC3 has a ubiquitin-like fold (Ubl) that belongs to the autophagy-related 8 (ATG8) protein family. A Ubl conjugation of MAP1LC3 by the phospholipid phosphatidylethanolamine (PE) is an essential process for the formation of autophagosomes. MAP1LC3 is cleaved by cysteine protease ATG4 and then conjugated with PE by E1-like enzyme ATG7 and ATG3, an E2-like enzyme. The Ubl conversion of MAPLC3 is known as a marker of autophagy-induction. MAP1LC3A staining patterns are used for different cancer diagnostic.

 191-276 7.97e-19

ubiquitin-like (Ubl) domain found in autophagy-related ubiquitin-like protein; Autophagy is an essential intracellular process that targets large protein complexes, bacterial pathogens, and organelles for degradation. The autophagy-related ubiquitin-like proteins, such as Saccharomyces cerevisiae Atg8p, undergo a unique ubiquitin-like (Ubl) conjugation, a process essential for autophagosome formation. Ubiquitin is a protein modifier in eukaryotes that is involved in various cellular processes including transcriptional regulation, cell cycle control, and DNA repair. The ubiquitination process comprises a cascade of E1, E2 and E3 enzymes that results in a covalent bond between the C-terminus of ubiquitin and the epsilon-amino group of a substrate lysine. ATG8 family proteins undergo multistep modifications by the E1-like (ubiquitin activating) enzyme ATG7, and the E2-like (ubiquitin conjugating) enzyme ATG3. The mammalian ATG8 family is classified into three subfamilies: i) MAP1LC3 (microtubule associated protein 1 light chain 3) which includes MAP1LC3A, MAP1LC3B, MAP1LC3B2, and MAP1LC3C, ii) GABARAP (GABA type A receptor associated protein) which includes GABARAP, GABARAPL1, and GABARAPL3, and iii) GABARAPL2 (GABA type A receptor associated protein like 2), also known as GATE-16 (golgi-associated adenosine triphosphatase enhancer of 16 kDa).
