Required for oocyte maturation, embryonic development, germline proliferation and initiation of meiosis during spermatogenesis. Required for chromosome structure during mitosis and negative regulation of nuclear envelope breakdown. Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. WEE1 subfamily.

CTD nuclear envelope phosphatase 1 homolog; Serine/threonine protein phosphatase that may dephosphorylate and activate lipin-like phosphatases. Lipins are phosphatidate phosphatases that catalyze the conversion of phosphatidic acid to diacylglycerol and control the metabolism of fatty acids at different levels. May indirectly modulate the lipid composition of nuclear and/or endoplasmic reticulum membranes and be required for proper nuclear membrane morphology and/or dynamics. May also indirectly regulate the production of lipid droplets and triacylglycerol.

LEM protein 2; Essential protein involved in chromosome segregation and cell division, probably via its interaction with lmn-1, the main component of nuclear lamina. Has some overlapping function with emr-1. May play a role in radiation-induced DNA damage repair response.
