  sub:_5 prov:value """Here we tested whether the related human LRIG1 (also called Lig-1) protein can act
as a negative regulator of EGF receptor and its relatives, ErbB2, ErbB3, and ErbB4.
We observed that in co-transfected 293T cells, LRIG1 forms a complex with
each of the ErbB receptors independent of growth factor binding. We further observed
that co-expression of LRIG1 with EGF receptor suppresses cellular receptor
levels, shortens receptor half-life, and enhances ligand-stimulated receptor ubiquitination.""" ;
