We have isolated and characterized cDNA clones encoding a novel human
homeobox gene, MOX2, the homologue of the murine mox-2 gene. The MOX2
protein contains all of the characteristic features of Mox-2 proteins
of other vertebrate species, namely the homeobox, the polyhistidine st
retch, and a number of potential serine/threonine phosphorylation site
s. The homeodomain of MOX2 protein is identical to all other vertebrat
e species reported so far (rodents and amphibians). Outside the homeod
omain, Mox-2 proteins share a high degree of identity, except for a fe
w amino acid differences encountered between the human and the rodent
polypeptides. A polyhistidine stretch of 12 amino acids in the N termi
nal region of the protein is also conserved among humans, rodents, and
(only partly) amphibians. The chromosomal position of 7p22.1-p21.3. (
