Fig. 3. Localisation of myc-tagged IRSp53 constructs in B16 cells. (a) Myc-tagged
IRSp53 constructs. RCB, CRIB and SH3 indicate Rac binding region, CRIB motif
and SH3 domain, respectively. Number indicates the position of corresponding
amino acid residue. (b-i) Cells transfected with myc-
SH3, myc-SH3 or
myc-RCB, as indicated, and immunolabelled with monoclonal anti-myc antibody
9E10 (b,d,f,h) and rhodamine-phalloidin (c,e,g,i). Arrows and arrowheads
indicate the tips of filopodia and lamellipodia, respectively. Bars, 10
µm.
