CKb12, or Chemokine (C-C motif) ligand 16, is a human gene encoded by CCL16. It may also be known as: C-C motif chemokine 16; Chemokine CC-4; HCC-4; Chemokine LEC; IL-10-inducible chemokine; LCC-1; Liver-expressed chemokine; Lymphocyte and monocyte chemoattractant; LMC; Monotactin-1; MTN-1; NCC-4; Small-inducible cytokine A16; ILINCK; LEC; NCC4; SCYA16; SCYL4. The encoded protein has an amino acid length of 120 and a mass of 13.6 kDa. CKb12 is a member of the Intercrine beta (chemokine CC) family. Homologs of this gene exist in other organisms, including: Arabidopsis.
