Abstract: | An EST (gb/AA115239) with high identity to the mouse cytokine signal transduction inhibitor genemmSOCS-2 was selected in GenBank EST database by the homologous screening method. The cDNA with the same sequence of the EST was got
in human placenta cDNA library by PCR and a 1011 bp cDNA fragment was selected using above cDNA as probes to perform walking
hybridization in placenta cDNA library. The cDNA fragment contains one 594 bp open reading frame (ORF) which encodes 198 amino
acid residues. It was proved to be novel after NCBl database screening. Homology comparison showed that this gene has 93%
identity tommSOCS-2 at the amino acid level and it has high identities to other related genes in SH2 domain and SOCS box, so it was namedhumSOCS-2 and the accession number in GenBank is gb/AF020590. The expression analysis showed that the gene is expressed obviously higher
in prostate than in other 15 human tissues. |
