Fig. 8. Transient expression of hARL5 or its mutants and HP1
in COS-7 cells.
COS-7 cells co-transfected with Flag-tagged HP1-
and GFP-tagged
constructs of hARL5, hARL5(Q80L), hARL5(T35N), hARL5(dC), hARL5(dMIR), or
hARL5(Q80LdMIR) were grown on glass coverslips, fixed with formaldehyde, and
incubated with mouse anti-Flag (d,h,l,p,t,x) or mouse anti-nucleolin
(nucleolar marker) antibodies. Coverslips were mounted on Mowiol (supplemented
with Hoechst 33258; b,f,j,n,r,v) and inspected with a Zeiss Axiophot equipped
for epifluorescence. Phase-contrast microscopy (a,e,i,m, q,u) and GFP-hARL5
fluorescence (c,g,k,o,s,w; green) are shown. Nucleolins are indicated by
arrows. Co-localization of HP1-
and hARL5(Q80L) is indicated by
arrowheads. Bar, 10 µm.
