Sequence analysis
Human CCL28 is encoded by an RNA transcript of 373 nucleotides and a gene with four exons. The gene codes for a 127-amino acid CCL28 protein with a 22-amino acid N-terminal signal peptide. It shares 76% nucleic acid identity and 83% amino acid similarity to the equivalent molecule in mouse. Sequence analysis has revealed CCL28 to be most similar to another CC chemokine called CCL27.
