Figure 4: Structural correlates of p70. Panel (a)—Comparison of amino-termini (amino acids 25–44) sequences in different albumin proteins and p70. hALB, human; bALB, bovine; mALB, mouse; rALB, rat albumin. X, unidentified amino acid in p70. Conserved amino acids are in bold. Panel (b)—affinity of p70 antibody to proteins in cell extracts obtained from mouse vSMCs or rat and mouse livers. Different amounts of extracts were fractionated and probed with p70 antibody to ascertain relative protein abundance. Similar results were seen in 2 independent experiments.
