概述

CXCL12 also known as SDF-1 is belonging to the CXC chemokine family.Rat CXCL12 is expressed as two isoforms that differ only in the C-terminal tail.And both SDF-1 isoforms undergo proteolytic processing of the first two N-terminal amino acids.Contrast to 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.SDF-1 is highly conserved between species,rat CXCL12α shares approximately 96%amino acid sequence identity with human CXCL12α.
