Plant homeodomain finger

Gozani, O. and Yang, W. (2007) The plant homeodomain finger of RAG2 recognizes histone H3 methylated at both lysine-4 and arginine-2. Proceedings of the National Academy of Sciences of the United States of America, 104, 18993-18998.

With regard to specificity, plant homeodomain (PHD) fingers constitute the most diverse class of histone binding modules. These modules recognize lysine in unmodified, mono-, di- and trimethylated states. Although not stmcturally related. 

Plant homeodomain (PHD) fingers recognize different methylation states of histone H3 Lys4 (H3K4).
