Fig 1. Predicted nucleosome hindrance at Ly49 forward promoter 1.

Probable nucleosome position across the Ly49 gene family in the C57BL/6 mouse was determined using a 4^th order Hidden Markov model, based on the genomic sequence affinity for nucleosome binding. For each Ly49 gene with an annotated Pro1 and/or Pro2 region, the proportion of bases covered by a nucleosome is indicated. Regions with over half the bases covered are coloured red, while regions with over half the bases exposed are coloured green.
