Protein–protein interaction studies with full-length or truncated
ERβ and MAD2. (A) Protein–protein interaction studies
with [S35]hMAD2 and mERβ. [S35]MAD2 was
incubated with GST beads alone or GST-mERβ beads followed by
SDS/PAGE and autoradiography. The first shows 15% of
[S35]MAD2 input. (B) Protein–protein
interaction studies with [S35]hMAD2 and full-length ERβ
or several ERβ truncation mutants. [S35]MAD2 was
incubated with GST beads alone, GST-full-length ERβ (GST-rERβ),
GST-mERβ173–485, GST-mERβ1–208 beads, or GST-mERβ 173–208,
followed by SDS/PAGE and autoradiography. The first lane shows 7% of
[S35]MAD2 input.
