General annotation (Comments)
| Function | Probable histone methyltransferase involved in chromatin modification and/or remodeling in meiotic germ cells. May act redundantly with mes-3 and mes-4 proteins. Required for RNAi. Functions as an antagonist of hpl-1 and hpl-2 activity in growth and somatic gonad development. Ref.2 Ref.3 Ref.4 Ref.5 |
| Catalytic activity | S-adenosyl-L-methionine + L-lysine-[histone] = S-adenosyl-L-homocysteine + N(6)-methyl-L-lysine-[histone]. |
| Subcellular location | Nucleus. Note: Localized in mitotic and mid-late-stage meiotic nuclei but is undetectable in early pachytene nuclei. Ref.2 |
| Tissue specificity | Expressed in all cells of embryo. In L1 larva, it is predominantly expressed in Z2 and Z3 primordial germ cells. In adults, it is predominantly expressed in the germline. Ref.2 |
| Developmental stage | Expressed throughout embryogenesis. |
| Sequence similarities | Contains 1 post-SET domain. Contains 1 RRM (RNA recognition motif) domain. Contains 1 SET domain. |
