( A ) Location of the dentin sialophosphoprotein (DSPP) and other SIBLING genes on human chromosome 4. ( B ) Homologous region on chicken chromosome 4 and putative location of DSPP. Note that the SIBLING cluster is more compact in chicken than in human. OC116 and MEPE are orthologs. ( C ) Result of the similarity search in the candidate region between DMP1 and SPARCL1 using human DSPP exon 2. Chicken Ψ-DSPP exon 2 was found 5,800 bp from DMP1. ( D ) Alignment of chicken and crocodile DSPP exon 2 showing 54% nucleotide identity. See the NCBI website for gene descriptions corresponding to the symbols.
