Tag Info

N-terminal His-tagged/Tag-Free
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.

Storage

Store at -20°C, for extended storage, conserve at -20°C or -80°C.

Shelf Life

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

Notes

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function(From Uniprot)

Ubiquitin-like protein which plays a key role in the innate immune response to viral infection either via its conjugation to a target protein (ISGylation) or via its action as a free or unconjugated protein. ISGylation involves a cascade of enzymatic reactions involving E1, E2, and E3 enzymes which catalyze the conjugation of ISG15 to a lysine residue in the target protein. Exhibits antiviral activity towards both DNA and RNA viruses. The secreted form of ISG15 can: induce natural killer cell proliferation, augment lymphokine-activated-killer (LAK) activity, induce dendritic cell maturation, act as a chemotactic factor for neutrophils and act as a IFN-gamma-inducing cytokine playing an essential role in antimycobacterial immunity. The secreted form acts through the integrin ITGAL/ITGB2 receptor to initiate activation of SRC family tyrosine kinases including LYN, HCK and FGR which leads to secretion of IFNG and IL10; the interaction is mediated by ITGAL. In response to IFN-tau secreted by the conceptus, may ligate to and regulate proteins involved in the release of prostaglandin F2-alpha (PGF), and thus prevent lysis of the corpus luteum and maintain the pregnancy.

Gene References into Functions

Data suggest that ISG15 is involved in early blastocyst/embryo development; ISG15 appears to regulate gene expression in developing blastocyst; specifically, ISG15 is required for up-regulation of IFNT expression in blastocyst development. (ISG15 = ubiquitin-like protein ISG15, interferon-stimulated gene 15 protein; IFNT = interferon-tau) PMID:27165775
ISG 15 gene expression is upregulated during 16-18 days of pregnancy and could be used as an early pregnancy marker in dairy cows, especially in heifers. PMID:27766692
ISG15, UBE1l and UBCH8 genes are significantly upregulated in the artificially inseminated pregnant cows. PMID:27802914
