Syntenic mapping of the
RLN1/RLN2/INSL4/INSL6 locus in
tetrapods. Schematic representation of relaxin locus syntenic to the
RLN1/RLN2/INSL4/INSL6 locus on human
chromosome 9 in chimpanzee (P. troglodytes), Rhesus monkey (M.
mulatta), cow (B. taurus), dog (C. familiaris), mouse
(M. musculus), rat (R. norvegicus), the gray short-tailed
opossum (M. domestica), platypus (O. anatinus), chicken
(G. gallus), and the clawed frog (X. tropicalis). The
relaxin family genes on the syntenic relaxin family locus B (RFLB)
locus of different vertebrates are indicated by black rectangles,
whereas, neighboring genes are indicated by blank rectangles
(35). The chromosomal numbers
or the genomic contig numbers are indicated at the bottom of the
schematic representation of each genomic fragment. The positions of select
genes in the genomes of human and X. tropicalis are also indicated
(*), part of the syntenic region on chromosome 8 of cow is mapped
to unknown chromosome in the GenBank™.
