We previously described the cDNA sequence of HPC-1/syntaxin 1A (HGMW-a
pproved symbol STX1A) from rat and bovine brains. HPC-1/syntaxin 1A be
longs to the syntaxin family and is apparently involved in intracellul
ar membrane transport and the exocytosis of neurotransmitters. In this
study, we isolated the cDNA and the genomic DNA clone for human HPC-1
/syntaxin 1A and carried out gene mapping. Polymerase chain reaction a
nalysis of human/rodent somatic cell hybrid panels and fluorescence in
situ hybridization analysis using a genomic DNA clone provided eviden
ce that the gene for human HPC-1/syntaxin 1A maps to chromosome region
