Subcellular fractionation of proto-Lbc and onco-Lbc and their derived mutant products. (A) Proto-Lbc localizes to the P (particulate) fraction, and point mutation of the PH domain (WPH Proto) has no effect on this localization. The PP43 proto-Lbc deletion mutant product also localizes predominantly to the P fraction, while the α-HEL proto-Lbc deletion mutant shows some relocation to the S (soluble) fraction. The PS-1 product (the Proto-Lbc C terminus) localizes predominantly to the P fraction. (B) More than 50% of onco-Lbc localizes to the S fraction. A point mutation (WPH) or deletion (NOPH 5) product (indicated by arrow) of the onco-Lbc PH domain has no significant effect on onco-Lbc S or P fraction localization. (C) Endogenous or transfected RhoA (indicated by arrow) localizes predominantly to the S (soluble) fraction, as previously reported (1).
