概述

CXCL12 also known as SDF-1 is belonging to the CXC chemokine family.It is encoded by the CXCL12 gene.In recently study,Human CXCL12 is expressed as six isoforms that differ only in the C-terminal tail.And all SDF-1 isoforms undergo proteolytic processing of the first two N-terminal amino acids.Contrast to the canonical sequence SDF-1β,SDF-1α is shorter by four amino acids at the C-terminal tail.On the cell surface,the receptor for this chemokine is CXCR4 and syndecan4.CXCL12 is strongly chemotactic for T-lymphocytes,monocytes,but not neutrophils.CXCL12 is a very important factor in carcinogenesis and the neovascularisation linked to tumor progression.
