ABSTRACT
<p><b>OBJECTIVE</b>To investigate the biological functions of TTG1A in liver fibrosis.</p><p><b>METHODS</b>Yeast two-hybrid system was used to screen proteins associated with TTG1A. Briefly, the coding sequence of TTG1A was cloned into pGBKT7 vector, and the recombinant plasmid was transformed into yeast cells AH109 ( a type), then these cells were mated with yeast cells Y187 (a type) transformed with human leukocyte cDNA library plasmid pACT2. The obtained diploid yeast cells were plated on synthetic dropout nutrient medium containing X-alpha-gal for double selection. The plasmids from positive colonies were transformed into E.coli and sequenced.</p><p><b>RESULTS</b>The recombinant yeast expression vector pGBKT7-TTG1A was successfully constructed. Nineteen TTG1A binding proteins, including Homo sapiens major histocompatibility complex, class II DP beta 1 (HLA-DPb1), Homo sapiens ribosomal protein L30 (RPL30), Homo sapiens nucleophosmin Homo sapiens nucleobindin 2 (NUCB2), Homo sapiens ash2, variant Gaucher disease and variant metachromatic leukodystrophy, MORF4L1, Homo sapiens ubiquitin-conjugating enzyme E2L3 (UBE2L3), APOA1, Homo sapiens lectin, and galectin 1, were identified.</p><p><b>CONCLUSIONS</b>This study may help to elucidate the molecular function of TTG1A.</p>
