Self-association of Lcaf protein.
A, elution profiles of the h:Lcaf complex (top) and h:Lcaf protein (bottom) in gel filtration chromatography. Numbers at the top indicate fraction numbers of the chromatography. Elution of markers is shown on the horizontal axis. M and IN at the top are the molecular mass marker and input protein fraction on chromatography, respectively. B, self-association of Lcaf in yeast two-hybrid analysis. HIS3 gene was used as a reporter gene. Top, schematic structures of Lcaf hybrid proteins. LUFS, the conserved domain, named after the four founding members LUG, LUH (for LEUNIG_HOMOLOG), yeast Flo8, and human SSDP. Bottom, each yeast transformant was inoculated on an SD agar plate containing 10 mm 3-AT without histidine or on SD agar with histidine.
