General annotation (Comments)
| Function | Phosphorylates diacylglycerol (DAG) to generate phosphatidic acid (PA). Plays a key role in promoting cell growth. Activates the Ras/B-Raf/C-Raf/MEK/ERK signaling pathway induced by EGF. Regulates the recruitment of RAF1 and BRAF from cytoplasm to membranes and their heterodimerization. Ref.1 Ref.6 |
| Catalytic activity | ATP + 1,2-diacylglycerol = ADP + 1,2-diacyl-sn-glycerol 3-phosphate. Ref.1 |
| Subunit structure | Isoform 1 forms homooligomers through the SAM domain. Isoform 1 is also able to form heterooligomers with SAM domain-containing isoforms of DGKD. Oligomerization of isoform 1 inhibits its catalytic activity. Interacts with RAF1 and BRAF. Ref.1 Ref.6 |
| Subcellular location | Cytoplasm. Cell membrane. Note: Translocated from the cytoplasm to endosomes in response to stress stimuli. Isoform 2 is rapidly relocated back to the cytoplasm upon removal of stress stimuli, whereas isoform 1 exhibits sustained endosomal association. Translocates from the cytoplasm to the cell membrane in the presence of active GTP-bound form of HRAS. Ref.1 Ref.6 |
| Tissue specificity | Isoform 2 is ubiquitously expressed. Isoform 1 is expressed only in testis, kidney and colon. Ref.1 |
| Post-translational modification | Phosphorylated; does not inhibit catalytic activity. Ref.1 |
| Sequence similarities | Belongs to the eukaryotic diacylglycerol kinase family. Contains 1 DAGKc domain. Contains 1 PH domain. Contains 2 phorbol-ester/DAG-type zinc fingers. Contains 1 SAM (sterile alpha motif) domain. |
| Sequence caution | The sequence BAC05280.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. |
Ontologies
Alternative products
| This entry describes 4 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q86XP1-1) Also known as: DAG kinase eta-2; DGKH-2; This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: Q86XP1-2) Also known as: DAG kinase eta-1; DGKH-1; The sequence of this isoform differs from the canonical sequence as follows: 1148-1220: VQKWGTEEVA...LGRSTPQSEV → GSGDTESGSCEANSPGN | ||||||
| Isoform 3 (identifier: Q86XP1-3) The sequence of this isoform differs from the canonical sequence as follows: 1-136: Missing. 1191-1191: K → KNTVGEKRDTKENGKHM | ||||||
| Note: No experimental confirmation available. | ||||||
| Isoform 4 (identifier: Q86XP1-5) The sequence of this isoform differs from the canonical sequence as follows: 1-136: Missing. |
