Interaction of β-2 glycoprotein I clones with apo(a)KIV2 bait in the two hybrid genetic screen. Positive clones obtained on screening of a human liver cDNA library are shown. The distinct domains of β-2 glycoprotein I are shown on the top. The minimal consensus binding domain for apo(a)KIV2 is indicated by dotted lines. SP, signal peptide; SCR, short consensus repeat.
