  sub:_5 prov:value """Interestingly, when lysates from co-transfection experiments were blotted with anti-receptor
antibodies, a loss of EGFR, ErbB2, ErbB3, and ErbB4 was observed in
the presence of LRIG1, but no loss of insulin receptor was observed despite very
efficient transfection of these cells (Fig. 1C, compare lanes 1 and 3 in all panels).
These observations suggest that a functional consequence of LRIG1 interaction
with receptor tyrosine kinases may be suppression of receptor levels to lower
the efficiency of signaling.""" ;
