products description :
Description: The AIF1 Human Recombinant contains a total of 155 amino acids having a molecular Mass of 17.7kDa. The Human AIF1 is fused to a 9 amino acid long N-terminal His tag. Introduction: Human AIF1 protein shares 98% homology/identity with that of rat. AIF1 is expressed in macrophages and neutrophils. The expression of AIF1 transcripts is upregulated by IFN-g in rat macrophages. AIF1 is expressed selectively in human macrophage-like cell lines, and in a subset of CD68(+) macrophages in the interstitial and perivascular spaces of human heart allografts. In quiescent cultured human vascular smooth muscle cells synthesis of AIF1 is induced by IFN-g, IL1b, and conditioned medium of T-cells. Overexpression of AIF1 in human VSMCs results in enhanced growth of these cells. AIF1 is expressed during apoptosis rat mammary gland and ventral prostate tissues. Allograft Inflammatory Factor 1 is expressed by several tumor-associated activated macrophages and microglial cells in rat and human gliomas. There is an evident relationship of AIF1-expressing activated macrophages and microglial cells with tumor malignancy in humans.

ncbi summary :
This gene is induced by cytokines and interferon. Its protein product is thought to be involved in negative regulation of growth of vascular smooth muscle cells, which contributes to the anti-inflammatory response to vessel wall trauma. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2008]
uniprot summary :
AIF1: Actin-binding protein that enhances membrane ruffling and RAC activation. Enhances the actin-bundling activity of LCP1. Binds calcium. Plays a role in RAC signaling and in phagocytosis. May play a role in macrophage activation and function. Promotes the proliferation of vascular smooth muscle cells and of T- lymphocytes. Enhances lymphocyte migration. Plays a role in vascular inflammation. 3 isoforms of the human protein are produced by alternative splicing. Protein type: Cytoskeletal. Chromosomal Location of Human Ortholog: 6p21.3. Cellular Component: perinuclear region of cytoplasm; lamellipodium; cytoplasm; actin filament; perikaryon; nucleus; cytosol; phagocytic cup. Molecular Function: actin filament binding; calcium ion binding. Biological Process: actin filament bundle formation; positive regulation of nitric oxide biosynthetic process; negative regulation of smooth muscle cell proliferation; positive regulation of smooth muscle cell proliferation; Rac protein signal transduction; microglial cell activation; cellular response to hormone stimulus; actin filament polymerization; positive regulation of muscle hyperplasia; cellular response to extracellular stimulus; positive regulation of T cell proliferation; response to axon injury; positive regulation of protein amino acid phosphorylation; phagocytosis, engulfment; inflammatory response; response to electrical stimulus; negative regulation of apoptosis
