Structure of the murine E-selectin ligand 1 (ESL-1) gene and assignment to Chromosome 8.

A 150-kDa glycoprotein designated in the mouse as E-selectin ligand-1 (ESL-1; gene symbol Selel) was first isolated based on its ability to function as a ligand for E-selectin. The gene appears equivalent to that for membrane glycoprotein MG160 encoded in the human by the locus for Golgi apparatus protein 1 (GLG1). ESL-1 is also highly homologous to the chicken cysteine-rich fibroblast growth factor receptor (CFR). We describe the genomic structure and chromosomal localization of the Selel locus. The gene is encoded by 27 exons and extends over approximately 75 kb. It maps to murine Chromosome (Chr) 8 in a region homologous to human Chr 16q where the GLG1 locus maps, further indicating that Selel and GLG1 are mouse and human equivalents of the same gene.
