Abstract
Sphingolipid activator protein SAP-1 is required for the enzymatic hydrolysis of GMI ganglioside and sulfatide. The gene coding for SAP-1 was previously mapped to human chromosome 10 using monospecific antibodies prepared against SAP-1 in synteny analysis of somatic cell hybrids. In this study, we used a cDNA probe for SAP-1 and in situ hybridization to regionally localize theSAP1 gene to the long arm of chromosone 10, region q21–22. Additional mapping data using cell hybrids containing partial chromosome 10 and skin fibroblasts with trisomy 10p are consistent with the in situ hybridization mapping results.This publication has 12 references indexed in Scilit:
