CC -!- FUNCTION: Forms with the serine/threonine protein phosphatase CTDNEP1
CC an active complex which dephosphorylates and may activate LPIN1 and
CC LPIN2. LPIN1 and LPIN2 are phosphatidate phosphatases that catalyze the
CC conversion of phosphatidic acid to diacylglycerol and control the
CC metabolism of fatty acids at different levels. May indirectly modulate
CC the lipid composition of nuclear and/or endoplasmic reticulum membranes
CC and be required for proper nuclear membrane morphology and/or dynamics.
CC May also indirectly regulate the production of lipid droplets and
CC triacylglycerol. {ECO:0000269|PubMed:22134922}.
CC -!- SUBUNIT: Interacts with CTDNEP1; the complex dephosphorylates LPIN1 and
CC LPIN2. {ECO:0000269|PubMed:22134922}.
CC -!- INTERACTION:
CC Q8N9A8; O95476: CTDNEP1; NbExp=4; IntAct=EBI-5323455, EBI-5323433;
CC -!- SUBCELLULAR LOCATION: Nucleus membrane {ECO:0000269|PubMed:22134922};
CC Multi-pass membrane protein {ECO:0000269|PubMed:22134922}. Cytoplasm
CC {ECO:0000269|PubMed:22134922}. Note=Filamentous pattern in the
CC cytoplasm.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=3;
CC Name=1;
CC IsoId=Q8N9A8-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q8N9A8-2; Sequence=VSP_025126;
CC Name=3;
CC IsoId=Q8N9A8-3; Sequence=VSP_025127, VSP_025128;
CC -!- TISSUE SPECIFICITY: Muscle specific with lower expression in other
CC metabolic tissues. {ECO:0000269|PubMed:22134922}.
CC -!- SIMILARITY: Belongs to the CNEP1R1 family. {ECO:0000305}.
