The human chromosome 3 locus coding for hepatocyte growth factor-like prote
in/macrophage stimulating protein (HGFL/MSP) is homologous to two sets of a
mplified loci on human chromosome 1 at 1p36. One copy of one of the amplifi
ed loci (D1F15S1A) has been further characterized by restriction enzyme and
DNA sequence analysis. A total of 8331 bp of continuous sequence was deter
mined for this locus. The first 6878 bp of sequence is 96.1% identical to t
he HGFL/MSP gene, while there is no homology between the two genes followin
g nucleotide 6878. Based on the presence of a 5 bp deletion in putative exo
n 2 and several downstream stop codons it is very likely that this gene is
a pseudogene. Screening of a human liver cDNA library with a chromosome 1-s
pecific probe indicates that at least several other members of the chromoso
me 1 loci are transcribed.
