Lymphotactin antibody,Genetex,GTX10607

Human lymphotactin (Lptn)/XCL1, also named human SCM1 and ATAC, is a member of gamma or C subfamily of chemokines that lack two of the four invariant cysteine residues normally found in the CC and CXC chemokines and have an extended C-terminus. Human lymphotactin encodes a 114 amino acid precursor protein with a 21 amino acid predicted signal peptide. The gene for human and mouse lymphotactin has been mapped to chromosome 1. Human and mouse lymphotactin share approximately 60% amino acid sequence identity.The expression of lymphotactin is restricted to activated T cells such as activated CD8+ T cells and other class I MHC restricted T cells. Since lymphotactin is produced by lymphocytes and acts on lymphocytes, it is speculated that it is a messenger in T cell chemoattraction. Human lymphotactin is chemotactic for lymphocytes and NK cells. Its expression is abundant in some activated T cells such as activated CD8+ T cells and other class I MCH restricted T cells and is absent in CD4+ T cells. It has been shown that lymphotactin is a key regulator of lymphocyte motility and adhesion during acute allograft rejection. The specific receptor for lymphotactin is the orphan receptor XCR1 (GPR5).
