VAL-GLN-GLY-GLU-GLU-SER-ASN-ASP-LYS Usage And Synthesis

Biological Activity

β-interleukin i (163-171), human(c39h64n12o19), a peptide with the sequence val-gln-gly-glu-glu-ser-asn-asp-lys, mw= 1005. interleukins are a group of cytokines (secreted proteins/signaling molecules) that were first seen to be expressed by white blood cells (leukocytes). interleukin 1 alpha and interleukin 1 beta (il-1 alpha and il-1 beta) are cytokines that participate in the regulation of immune responses, inflammatory reactions, and hematopoiesis.interleukin-1 beta (il-1β) also known as catabolin, is a cytokine protein that in humans is encoded by the il1b gene. il-1β precursor is cleaved by caspase 1 (interleukin 1 beta convertase). cytosolic thiol protease cleaves the product to form mature il-1β. il-1β is a member of the interleukin 1 cytokine family. this cytokine is an important mediator of the inflammatory response, and is involved in a variety of cellular activities, including cell proliferation, differentiation, and apoptosis.figure1 formula of b-interleukin i (163-171), humanfigure2 structure of b-interleukin i

Biochem/physiol Actions

IL1B (interleukin 1 β) is an immune-activating cytokine. In presence of infection or cell stress, it gets converted into active mature form.
