Altered distribution of family members after mutation of K(X)KK(X) on FF motifs of the cytosolic domains of α₂ and β₁ proteins. Cotransfection of all five p24s in where either the KK (A and B) or the FF (C and D) motif has been altered to SS or AA, respectively, in both α₂ and δ₁. Altered redistribution and apparent cell surface staining can be seen with the KK/SS mutants (shown is α₂)(A). Remarkably, the unmutated members (shown is γ_3/4) (B) also reveals redistribution to the cell surface. Similarly, an apparent ER staining can be seen with the FF/AA mutants (shown is α₂)(C). This also leads to the apparent redistribution of the unmutated members to the ER (shown is γ_3/4)(D). Bar, 5 μm.
