FIG. 2. — The NBDs of HMGN1 and HMGN2 are interchangeable. (A) The interaction of HMGN1 with chromatin is dependent on intrinsic properties of HMGN rather than on the type of cell used. FRAP curves of HMGN1 in different cells are shown. (B) Quantitative FRAP analysis of HMGN1 and HMGN2 indicates that their chromatin-binding properties are identical. (C) Quantitative FRAP analysis of HMGN2 and HMGN3 indicates that their chromatin-binding properties are very similar. (D) Quantitative FRAP analysis of HMGN2 and NSBP1 indicates that their chromatin-binding properties are very similar. (E) Quantitative FRAP analysis of a swap mutant in which the NBD of HMGN1 was swapped with that of HMGN2. (F) Quantitative FRAP analysis of a swap mutant in which the NBD of HMGN2 was swapped with that of HMGN1. The FRAP analyses shown in panels B to F were done in MEFs.
