30590679-2	2019	We previously showed that mammalian HP1alpha is constitutively phosphorylated at its N-terminal serine residues by casein kinase II (CK2), and that this phosphorylation enhances HP1alpha"s binding specificity for nucleosomes containing lysine 9-methylated histone H3 (H3K9me).	histone h3	256-266	chromobox 5	Homo sapiens	36-44	
21245376-3	2011	Recombinant HP1alpha prepared from mammalian cultured cells exhibited a stronger binding affinity for K9-methylated histone H3 (H3K9me) than that produced in Escherichia coli.	histone h3	116-126	chromobox 5	Homo sapiens	12-20
