IL1A Protein (AA 113-271)

Catalog No. ABIN6253323

Product Details

Target: IL1A (Interleukin 1 alpha (IL1A))

Protein Type: Recombinant

Biological Activity: Active

Protein Characteristics: AA 113-271

Origin: Human

Source: HEK-293 Cells

Purpose: IL-1alpha (human) (rec.)

Specificity: Human IL-1alpha (aa 113-271).

Characteristics: Protein. Human IL-1alpha (aa 113-271). Source: HEK 293 cells. Endotoxin content: <0.01EU/μg protein (LAL test, Lonza). Lyophilized from 0.2μm-filtered solution in PBS. Purity: >95 % (SDS-PAGE). The most prominent members of the interleukin-1 (IL-1) superfamily are IL-1alpha and IL-1beta. They lack a signal peptide and are secreted by an unconventional, endoplasmic reticulum-Golgi-independent mechanism. IL-1alpha was reported to be more widely and constitutively expressed and has intracellular functions, but also acts locally in a membrane-bound form by activating IL-1R1. Additionally, passive release of IL-1alpha upon cell death can trigger a sterile inflammatory response to dying cells. The cleavage of IL-1alpha is not mediated by caspase-1 and is not required for binding to IL-1R1. Recently it has been observed that all activators of the inflammasome NLRP3/NALP3 induce the simultaneous secretion of IL-1alpha and IL-1beta. Although most activators fully rely on the inflammasome for IL-1alpha secretion, some induce the processing and secretion of IL-1alpha in an inflammasome-independent manner.
