描述:
P10, also named mob1 in rat and crg2 in mouse, is a member of the nonELRmotif
containing CXC chemokine subfamily and has been designated CXCL10. It is induced in
various cell types (including keratinocytes, endothelial cells, fibroblasts, smooth muscle
cells, monocytes/macrophages, astrocytes, neutrophils, hepatocytes, T cells, epithelial
cells and mesothelial cells) in response to stimulation by type I and/or type II interferon
as well as by LPS. IP10 has been shown to chemoattract activated CD4+ and CD8+ T cells,
activated NK cells and smooth muscle cells. It also induces the adhesion of activated T cells
to VCAM and ICAM. In addition, IP10 has been reported to antagonize the angiogenic
activity of FGF. IP10 binds to and activates CXCR3, the chemokine receptor that is shared
by MIG/CXCL9 and ITAC/CXCL11, two additional nonELR CXC chemokines that are induced
by interferon. Cotton rat IP10 cDNA encodes a 94 amino acid (aa) residue precursor protein
with a putative 21 aa signal peptide and a 73 aa mature protein with one potential Nlinked
glycosylation site. Mature cotton rat IP10 shares 66%, 64%, and 66% aa sequence identity
with rat, mouse and human IP10, respectively.
