Multiple sequence alignment for lymphotactins from various species. Sequences for human (GenBank accession no. AAC50164), rhesus (M. Kitabwalla and C. D. Pauza, unpublished results), mouse (AAA56752), rat (AAA69478), and chicken (AAB99904) were aligned with the program GCG. The N-terminal signal sequence which is removed posttranslationally is shown in italics. Residue numbering is for the mature extracellular species. Residues which are absolutely conserved across the five known species are in boldface type, and conserved basic residues are underlined in the human sequence.
