A transcriptional repressor complex that contains the lin-9, lin-35, lin-37, lin-52, lin-53, lin-5is involved in 4-, dpl-1 and efl-1 proteins, and is involved in cell fate specification.
Catalysis of the reaction: histone H3-serine (position 10) + ATP = histone H3-phosphoserine (position 10) + ADP. This reaction is the addition of a phosphate group to the serine residue at position 10 of histone H3.
